“Noises in the Night”: Dateline NBC Revisits the Homicide of Cassy Farrington August 14 2026
Dateline NBC returns to one of the most disturbing teen murder cases in Tennessee history with “Noises in the Night,” airing Friday, August 14, 2026, at 10/9c on NBC. Reported by Andrea Canning, the episode examines the November 2016 murder of 16-year-old Emma Walker, a Central High School cheerleader who was shot while she slept inside her family’s Knoxville home.
The case exposed a pattern of control, stalking, deception and fear surrounding Emma’s former boyfriend, William Riley Gaul. Investigators came to believe that the strange events Emma experienced before her death were connected to Gaul’s refusal to accept the end of their relationship. The investigation took an unusual turn when two of Gaul’s friends, Alex McCarty and Noah Walton, agreed to wear recording equipment and help police recover the weapon used in the shooting.
Gaul was convicted of first-degree murder and other offenses in 2018. His defense accepted that he fired the shots but argued that he had not intended to kill Emma. Prosecutors presented a different case, telling jurors that Gaul knew where Emma slept and fired into that section of her bedroom wall because she had ended their relationship.
“Noises in the Night” revisits Emma’s life, the warning signs before her murder, the police investigation, the undercover operation that led to Gaul’s arrest and the courtroom battle over whether the shooting was a reckless attempt to frighten Emma or a planned murder.

Who Was Emma Walker?
Emma Jane Walker was born on March 20, 2000, and grew up in Knoxville, Tennessee, with her parents, Jill and Mark Walker, and her younger brother. By the fall of 2014, she was attending Central High School, where she joined the cheerleading squad. She became part of a school community that would mourn her death two years later.
Emma was an honor student with interests that extended beyond cheerleading. She participated in Health Occupations Students of America, the National Beta Club and Young Life. Her academic interests reflected a career goal that had started to take shape before her death. Emma hoped to study nursing and had an interest in neonatal care.
Her mother, Jill Walker, has described Emma as compassionate, kind and full of life. Friends remembered a teenager with a large social circle who enjoyed cheering for Central High School’s football team. Those football games would form part of the setting in which Emma met Riley Gaul.
Emma was a junior when she died. At 16, she had begun making plans for college and a nursing career. Her murder ended those plans and left her family confronting a loss that would later lead them into advocacy work focused on dating violence and crime victims’ rights.
Emma Walker Meets Riley Gaul
Emma met William Riley Gaul during her freshman year at Central High School in 2014. Emma was 14 and Gaul was a 16-year-old junior who played wide receiver on the school’s football team. Gaul was dating another student when he became interested in Emma.
According to accounts presented during the case, Gaul told Emma that he planned to leave his girlfriend and promised to take Emma to prom. He went to the event with his existing girlfriend instead. Emma and Gaul began dating not long after.
People around the couple said the relationship did not appear threatening at first. Gaul could be attentive, polite and considerate. Jill Walker has said that her first impression of him was positive. He appeared to be a normal teenager and someone she had no reason to view as a danger to her daughter.
Gaul was also regarded as a strong student and an accomplished high school athlete. Friends described him as a jokester who did not fit the image of an aggressive football player. After graduating from Central High School, he enrolled at Maryville College and joined its Division III football program.
A Teenage Relationship Becomes Controlling
The relationship between Emma and Gaul lasted for about two years, with repeated breakups and reconciliations. Friends and family began seeing behavior from Gaul that they considered possessive and controlling. He did not want Emma spending time with people or participating in activities that he opposed.
Emma’s parents came to view the relationship as unhealthy. By October 2016, they had taken steps to separate the teenagers. Emma was grounded, and her parents told her that she could no longer maintain contact with Gaul.
The restrictions did not end the relationship at once. Emma and Gaul continued communicating as tensions increased. Emma tried to end the relationship in November 2016, but evidence presented in the case showed that Gaul struggled to accept her decision.
According to testimony and court records, Gaul had threatened suicide during parts of the relationship and used emotional pressure when Emma tried to leave him. After the breakup, investigators said his actions shifted toward conduct designed to frighten Emma, draw her attention and create situations in which he could portray himself as someone who could protect her.
The Staged Kidnapping Before Emma’s Murder
One of the most unusual events occurred on November 18, 2016, three days before Emma was found dead. Prosecutors said Gaul staged his own kidnapping as part of an attempt to draw Emma back into his life.
Emma received an anonymous message telling her to leave her house. She encountered Gaul outside, where he claimed that someone had kidnapped him. According to testimony from Emma’s friends, she did not accept his story and became angry when she concluded that the incident had been staged.
The deception became important at trial because Gaul’s defense would use it to support the argument that his conduct was based on attempts to scare Emma and then become her “hero.” The defense maintained that the later shooting was another reckless scheme that went wrong rather than a plan to kill her.
Prosecutors viewed the events through a different lens. They argued that the staged kidnapping showed the lengths Gaul had begun taking after losing control of the relationship. The state presented the incidents as part of an escalating pattern that ended with Emma’s murder.
A Man Dressed in Black Frightens Emma
Emma also reported seeing a person dressed in black near her home in the days before her death. The encounter frightened her. Friends testified that Emma sent messages expressing fear and concern that she could die.
After Emma’s murder, the person in black became part of the investigation. Detectives found black clothing among items connected to Gaul, together with materials that prosecutors linked to his attempts to hide or destroy evidence.
The incidents took on greater meaning when investigators placed them beside Gaul’s conduct surrounding the breakup. Detectives no longer saw the strange encounters as isolated events. They began examining whether someone had created those situations with the purpose of frightening Emma.
Emma had spent her last days dealing with events that made her feel unsafe. The danger was not presented as an unknown stranger in the prosecution’s case. Investigators came to believe it originated from someone she knew and someone who had refused to accept that their relationship was over.
Riley Gaul Steals His Grandfather’s Gun
On November 18, 2016, Gaul took a 9mm Glock handgun belonging to his grandfather from beneath the seat of a vehicle. The weapon would become one of the central pieces of evidence in the murder investigation.
When the gun disappeared, Gaul’s grandfather feared that his grandson might use it to harm himself. That concern reflected Gaul’s emotional state during the breakup. Investigators would reach a different conclusion about what he did with the firearm.
Before Emma’s death, Gaul spoke with friends about the gun. The fact that people close to him knew he possessed the weapon became crucial after detectives discovered that Emma had been shot with a 9mm firearm.
The missing Glock provided investigators with a potential link between Gaul and the shooting. Recovering it became a priority, but Gaul denied possessing his grandfather’s gun when police questioned him.
The Shooting at Emma Walker’s Home
During the early hours of November 21, 2016, Gaul left the Maryville area and traveled toward Emma’s home in the Sterchi Hills neighborhood of Knoxville. Evidence at trial placed him near the Walker residence during the period when investigators believed Emma was shot.
Gaul stood outside the house and fired two rounds through the exterior wall into the section of Emma’s bedroom where her bed was located. One bullet entered the room and struck Emma behind her left ear. Another ended up in or around her bedding.
Emma was asleep when the shots were fired. There was no confrontation inside the house and no indication that she had an opportunity to defend herself or seek help.
The manner of the shooting became important to the prosecution’s argument about intent. Prosecutors said Gaul knew Emma’s bedroom and knew where her bed sat against the wall. Firing two bullets into that area, they argued, showed that the shooting was not a random attempt to make noise outside the house.
Jill Walker Finds Her Daughter
At about 6 a.m. on November 21, Jill Walker went to Emma’s room to wake her. She found her 16-year-old daughter unresponsive in bed. Emma was not breathing.
Jill called 911. The first information reaching authorities raised the possibility of a suicide or another medical emergency. Nothing at first glance told Emma’s family that bullets had been fired through the exterior of their home.
A forensic technician examining the room noticed a bullet hole in the wall. That discovery transformed the nature of the response. When investigators examined the room and the exterior of the house, they found more evidence showing that Emma had been attacked from outside.
Detective Allen Merritt and other members of the Knox County Sheriff’s Office Major Crimes Division found two shell casings outside the home. One bullet had struck Emma. The evidence established that someone had approached the Walker residence during the night and fired into her bedroom.
Detectives Turn Their Attention to Riley Gaul
Investigators began interviewing Emma’s family, classmates and friends. Gaul’s name appeared throughout those conversations because of his relationship with Emma and the turmoil surrounding their breakup.
Alex McCarty, one of Gaul’s friends, told investigators that Gaul had taken his grandfather’s gun during the weekend Emma was killed. That information became significant when authorities connected the shooting to a 9mm weapon.
When police questioned Gaul, he denied having the gun. Investigators also examined his movements and communications. Cell phone evidence contradicted parts of his account of where he had been during the night of the murder.
Gaul’s college roommate testified that Gaul had been gone for much of the night and did not return to the dorm until about 4:45 a.m. Investigators also learned that Gaul had contacted friends about firearms and evidence and had become concerned about what those friends might tell police.
Gaul Tries to Stop His Friends From Talking
After police began interviewing people in Gaul’s circle, his communications with his friends attracted more attention. Evidence showed that Gaul urged them not to continue cooperating with investigators.
According to evidence presented in court, Gaul suggested that friends discredit information they had given investigators by claiming they had been drinking or using drugs. Such statements strengthened police concerns that Gaul was attempting to control the developing investigation.
He also questioned why they had told police about the missing gun. The messages suggested that the weapon was a source of concern for Gaul at the same time detectives were trying to locate it.
For McCarty and Noah Walton, Gaul’s conduct created a dilemma. They had known him as a friend. They were also beginning to believe that he possessed the gun used to kill Emma.
Alex McCarty and Noah Walton Agree to Help Police
McCarty and Walton made a choice that became one of the defining developments in the case. The two teenagers agreed to assist the Knox County Sheriff’s Office and record conversations with Gaul.
Investigators equipped them with microphones, a transmitter and hidden recording equipment. Walton invited Gaul to his house under the pretext that the group would spend time together and play video games.
The plan carried personal risk. McCarty and Walton needed Gaul to believe that they remained his friends while detectives listened to what was happening. They could not allow him to discover that they were working with police.
Their goal was not limited to obtaining incriminating statements. Investigators hoped Gaul would lead the two young men to the missing Glock, providing the physical evidence needed to connect him with Emma’s death.
The Undercover Operation Leads to the Murder Weapon
During the recorded interaction, Gaul continued discussing the investigation and denied killing Emma. The conversation then moved toward the missing gun and what should be done with it.
Gaul proposed taking the weapon to a bluff near the Tennessee River, where investigators believed he intended to dispose of it. The group stopped at a family residence where Gaul had hidden evidence.
The gun was concealed with other items, including gloves, trash bags, tennis shoes, black tape and dark clothing. Those materials gained importance because of reports that Emma had encountered a person dressed in black before her death.
When the weapon appeared, the young men gave police the information needed to move in. Gaul was arrested before the gun could disappear. The operation gave detectives access to the firearm and other physical evidence that prosecutors would use at trial.
The actions of McCarty and Walton became central to the case. Investigators credited them with helping prevent the destruction of evidence and giving law enforcement the chance to recover a weapon believed to have been used in Emma’s murder.
Physical and Digital Evidence Builds the Case
The Glock was not the only evidence presented against Gaul. Investigators assembled forensic, digital and witness evidence as prosecutors prepared for trial.
Cell phone records played a major role. Prosecutors presented location information placing Gaul in Knoxville during the hours surrounding the shooting, undermining his account of his movements. His roommate’s testimony also established that Gaul returned to Maryville College at about 4:45 a.m.
Investigators searched Gaul’s vehicle and recovered items that included shoes, gloves, black clothing and other materials. Testing connected Gaul’s DNA with a shoe and sweatshirt. DNA testing on the gun did not produce a conclusive result, but prosecutors did not rely on the weapon alone to prove their case.
The prosecution also used the trajectory of the gunshots and Gaul’s knowledge of Emma’s room. The state maintained that he knew where her bed was positioned and fired into that location.
Riley Gaul Is Charged With Emma Walker’s Murder
A Knox County grand jury indicted Gaul on a series of charges stemming from Emma’s death and the conduct surrounding it. They included first-degree premeditated murder, felony murder, stalking, tampering with evidence, reckless endangerment, a firearm offense and theft connected with his grandfather’s Glock.
Gaul was 18 at the time of the murder. His case drew national attention because of the ages of those involved, the shooting through Emma’s bedroom wall and the role Gaul’s friends played in helping investigators.
Gaul’s family posted a $1 million bond while the case moved toward trial. His defense attorney, Wesley Stone, sought additional preparation time, and the trial was moved into 2018.
The central question would not be whether Gaul had fired the weapon. By the end of the trial, the defense accepted that point. The dispute concerned Gaul’s state of mind and whether he intended to kill Emma.
The Murder Trial Begins in 2018
Gaul’s trial opened in Knox County Criminal Court at the end of April 2018 before Judge Bobby R. McGee. Testimony began on May 1 and continued through the following week.
Emma’s family described the morning she was found dead. Neighbors, investigators, forensic personnel, friends and people connected to Gaul testified about the relationship, the events before the murder and the investigation.
Jurors heard Jill Walker’s 911 call. They saw photographs and video from Emma’s bedroom and heard evidence concerning the two bullet holes in the house. Investigators explained how the crime scene had changed the case from what first appeared to be a possible suicide into a homicide investigation.
Emma’s friends described the breakup, Gaul’s conduct and the staged kidnapping. They also testified about Emma’s fear after she reported seeing a person dressed in black near her home.
Prosecutors Argue the Shooting Was Planned
Assistant district attorneys Kevin Allen and Molly Martin presented the state’s case. Prosecutors argued that Gaul killed Emma because he could not accept losing control of the relationship.
The state focused on motive, Gaul’s possession of the stolen handgun, his location during the shooting, the direction of the bullets and his conduct after the murder. Prosecutors said the trajectory showed that Gaul had targeted the area where Emma slept.
The fact that he fired twice supported the state’s argument that the shooting was purposeful. Prosecutors rejected the idea that Gaul had picked a random section of the wall for a scare tactic.
The prosecution also pointed to Gaul’s actions after Emma’s death. His attempts to influence what friends told police and his plan to dispose of the weapon were presented as evidence of consciousness of guilt.
During closing arguments, prosecutors described the killing as calculated and targeted. They told jurors that Gaul knew where Emma’s head would be when she was in bed.
The Defense Says Gaul Wanted to Scare Emma, Not Kill Her
Defense attorney Wesley Stone did not attempt to convince jurors that another person had fired the shots. The defense accepted that Gaul fired his grandfather’s gun but argued that he had not intended to kill Emma.
Stone portrayed Gaul’s conduct as a series of reckless schemes designed to regain Emma’s attention. The staged kidnapping had placed Gaul in a position where he could create danger and then present himself as someone Emma needed.
Under that theory, the shooting was another attempt to frighten Emma so Gaul could become her protector. The defense asked jurors to consider reckless homicide rather than first-degree premeditated murder.
The defense argued that the distinction between reckless behavior and a planned killing depended on Gaul’s state of mind when he pulled the trigger. Stone maintained that the prosecution had not proved beyond a reasonable doubt that Gaul wanted the bullets to strike Emma.
Prosecutors answered that argument by focusing on the placement of the shots, Gaul’s familiarity with the house and his conduct before and after the shooting.
The Jury Convicts Riley Gaul
The case went to the jury on May 8, 2018. After about four hours of deliberation, jurors found Gaul guilty of first-degree premeditated murder and the other offenses submitted to them.
The verdict meant the jury rejected the defense claim that Emma’s death resulted from a reckless scare tactic. Jurors accepted the prosecution’s position that the shooting constituted intentional, premeditated murder.
Gaul was convicted of first-degree premeditated murder and felony murder, along with firearm, reckless endangerment, stalking, tampering with evidence and theft offenses. The felony murder conviction was merged into the premeditated murder conviction for sentencing purposes.
The verdict brought the criminal trial to an end about a year and a half after Emma’s death. For her family, the verdict established legal responsibility for what had happened inside their home on November 21, 2016.
Riley Gaul Receives a Life Sentence
Judge McGee imposed the mandatory life sentence for the murder conviction. Under the sentence that applies to Gaul, he must serve 51 years before becoming eligible for parole.
Additional punishment was imposed for the remaining convictions, although the life term remains the controlling part of his sentence. Contemporary reporting described the practical result as life imprisonment with parole eligibility after 51 years.
At sentencing, Gaul continued to maintain that he had not intended to kill Emma. That position did not alter the jury’s verdict or the life sentence.
Gaul entered the Tennessee prison system as a convicted murderer. The case did not end there, as he pursued a series of challenges to his convictions through the state and federal courts.
Gaul Challenges His Conviction
In 2021, Gaul sought a new trial. Among his claims was an argument that the evidence had been insufficient to support his convictions. The trial court denied his request.
He appealed to the Tennessee Court of Criminal Appeals and raised twelve issues concerning the prosecution, trial procedure, evidence and verdict. On February 27, 2023, the appellate court upheld his murder conviction and the other principal convictions.
The appellate court modified the theft conviction because of the value classification involved, reducing that count from the felony level reflected in the original judgment to a Class A misdemeanor. The change did not disturb Gaul’s murder conviction or life sentence.
Gaul sought further review from the Tennessee Supreme Court, which declined to take the case in 2023. He then pursued review in the United States Supreme Court. The U.S. Supreme Court denied his petition on March 4, 2024.
Gaul Pursues Post-Conviction Relief
Gaul later opened another legal challenge through a petition for post-conviction relief. In the petition reported in 2025, he argued that he had received ineffective assistance from his trial attorney.
Among his claims was an argument concerning defense counsel’s concessions during closing statements. Gaul contended that his lawyer admitted evidence established his responsibility for theft and evidence tampering while failing to present the distinctions between murder offenses and reckless homicide in the manner Gaul believed was required.
Gaul also referred to an alleged change in Tennessee law that he claimed could reduce the length of time a person convicted of murder must serve before becoming eligible for parole. Reporting on the petition found that the legislative proposal matching his claim had not become law. A version introduced during the 2025 legislative session failed in the Tennessee Senate Judiciary Committee.
Public records correspondence from the Knox County District Attorney’s Office confirmed in June 2025 that Gaul had a post-conviction petition pending at that time. Records connected with Gaul also show a Knox County booking in February 2026 connected with a petition for post-conviction relief and his return to prison after the proceeding. Public reporting available in 2026 continues to list his murder conviction and 51-year parole requirement as intact.
Where Is Riley Gaul Now?
As of 2026, William Riley Gaul remains incarcerated for Emma Walker’s murder. Recent reporting lists him as serving his sentence at the Northwest Correctional Complex in Tiptonville, Tennessee.
His first-degree murder conviction remains in effect. The Tennessee Court of Criminal Appeals left the murder judgment intact in 2023, and later efforts to obtain review from higher courts did not overturn it.
Under the sentence imposed following his 2018 conviction, Gaul must serve 51 years before becoming eligible for parole. He will be an older man before the possibility of release arises if the sentence remains unchanged.
The continuing court filings have extended the legal history of the case, but they have not changed the central result of the trial: a jury determined that Gaul committed the premeditated murder of Emma Walker.
Emma Walker’s Murder Becomes a Warning About Teen Dating Violence
Emma’s death has become associated with efforts to raise awareness about unhealthy and dangerous teenage relationships. Her case demonstrates how behavior that begins with jealousy, control, emotional pressure and manipulation can progress into stalking and physical violence.
Friends and relatives saw signs that Gaul wanted control over Emma’s social life and resisted her attempts to separate from him. Prosecutors later placed those behaviors within the sequence of events that preceded the murder.
The staged kidnapping and frightening encounters outside Emma’s home showed how manipulation can extend beyond arguments between partners. Emma had reached the point where she expressed fear that she could die before the shots were fired into her room.
For families, schools and young people, her case has become a reference point in discussions about dating violence and the importance of taking threats, stalking and coercive conduct seriously.
Jill Walker Turns Her Daughter’s Death Into Advocacy
After Emma’s murder, Jill Walker began speaking about her daughter and the warning signs surrounding the relationship. Her work has included advocacy for crime victims and support for Marsy’s Law efforts in Tennessee.
Jill has described the goal as giving purpose to the pain created by Emma’s death. Her public statements have kept Emma at the center of the story rather than allowing the case to become a narrative focused on her killer.
The advocacy also places Emma’s murder within a broader discussion about how victims and their families are treated by the criminal justice system. Court proceedings can continue for years after a conviction, requiring families to revisit cases through appeals and post-conviction petitions.
For the Walker family, Emma remains more than the victim identified in court records. She was a daughter, sister, student, cheerleader and aspiring nurse whose life ended before she had the chance to enter adulthood.
Emma Walker’s Legacy Continues in Knoxville
Central High School students created the Emma Walker Memorial Scholarship after her death. The scholarship linked Emma’s name with the school community where she had spent much of her teenage life.
Knox County also dedicated the Emma Jane Walker Memorial Dog Park in her honor. Emma loved animals, making the project one way for the community to remember an aspect of her life apart from the circumstances of her death.
East Tennessee Children’s Hospital dedicated a neonatal intensive care unit room in Emma’s memory. The tribute carries a connection to her plans to pursue neonatal nursing, a career she had hoped to begin after college.
These memorials preserve a version of Emma that extends beyond a murder investigation and criminal trial. They reflect the student, friend and future nurse known by the people who shared her life.
The Two Friends Who Helped Solve Emma’s Murder
Alex McCarty and Noah Walton occupy an unusual place in the history of the case. They were teenagers asked to enter an undercover operation involving a friend they had begun to suspect was connected to a murder.
Their decision required them to maintain Gaul’s trust while police monitored their conversations. Gaul could not know they were carrying recording equipment or that officers were following developments.
The operation gave investigators access to evidence that might otherwise have disappeared. Gaul was preparing to dispose of his grandfather’s Glock when authorities intervened.
Investigators and Emma’s family have credited the two young men for their actions. Their involvement also gave “Noises in the Night” one of its most striking elements: the case was not broken through a traditional police interrogation alone, but through two young people who chose to help detectives investigate someone they knew.
Why the Evidence Against Riley Gaul Was So Important
No single piece of evidence carried the entire case. Prosecutors built their argument from the relationship history, Gaul’s access to the weapon, cell phone information, testimony about his movements, the shooting trajectory, physical evidence, his communications with friends and the attempt to dispose of the gun.
The stolen Glock linked Gaul to a weapon of the same type used in Emma’s killing. His communications showed concern about what friends were telling police. The undercover recordings captured his attempts to deal with evidence after Emma’s death.
The physical layout of Emma’s bedroom became another major component. Prosecutors argued that a person familiar with the house would know where Emma slept. Two shots fired from outside toward that location supported the state’s argument that she had been targeted.
That combination of evidence allowed prosecutors to move beyond proving that Gaul fired the gun. Their burden was to establish that he had acted with premeditation. The jury’s first-degree murder verdict showed that the prosecution met that burden.
“Noises in the Night” Revisits the Final Days of Emma Walker
Andrea Canning’s “Noises in the Night” places viewers inside the investigation that began when Jill Walker entered her daughter’s bedroom on November 21, 2016. What began as a confusing death scene became a murder case after investigators found the bullet holes and shell casings.
The episode reconstructs the events that had surrounded Emma before the shooting. Her breakup with Gaul, the staged kidnapping, the person dressed in black and Emma’s fear became pieces of the same timeline once detectives examined her final days.
The story then shifts to the friends who faced their own choice after police began asking questions. McCarty and Walton’s decision to work with investigators helped expose the location of the murder weapon and prevented evidence from disappearing.
At its core, however, “Noises in the Night” is the story of Emma Walker. She was 16 years old, weeks into her junior year, with plans to become a neonatal nurse. The criminal case provided an answer to who killed her and resulted in a life sentence, but no verdict could restore the future taken from her.
Dateline NBC Brings the Emma Walker Case Back to Television
The Emma Walker murder has remained part of the national true crime conversation because of the ages of those involved, the warning signs before the killing and the unusual investigation that followed. It has been examined by several television programs, and “Noises in the Night” remains Dateline NBC’s account of the case.
The episode also provides a record of how detectives transformed a shooting with no eyewitness inside Emma’s room into a case strong enough for a first-degree murder conviction. Interviews with Emma’s family, friends and investigators illustrate how information from different people filled gaps in the timeline.
More than nine years after Emma’s murder, Riley Gaul remains in prison and the conviction that sent him there remains in force. Emma’s family continues to preserve her memory through advocacy and public discussion of dating violence, while memorials in Knoxville connect her name with the ambitions and interests she had before her death.
Dateline NBC: “Noises in the Night” airs Friday, August 14, 2026, at 10/9c on NBC. The episode is reported by Andrea Canning and revisits the murder of Emma Walker, the investigation that exposed Riley Gaul and the two young men whose decision to help police played a crucial role in bringing the case before a jury.
