The Victim: LaNell Barsock
LaNell Barsock was a 29-year-old nurse who had built a fulfilling life in Palmdale. Known for her generosity, she not only cared for patients but also supported friends who were struggling. One of them, Marcel Fomotar, recalled how LaNell helped him adapt to life in America after arriving from Cameroon, calling her his “guardian angel.” She often gave freely to those around her, sharing textbooks, advice, and even clothing.
LaNell’s caring nature extended to her romantic relationships. It was through her compassion that she first connected with Louis Bonheur, a Haitian immigrant she gave a ride to after a nursing class. Their relationship developed quickly, with Bonheur eventually moving into LaNell’s home. However, behind closed doors, the relationship was marked by tension and emotional volatility.
The Crime Scene and a Misleading First Impression
On June 16, 2010, La’Rene Austin entered the Palmdale Sheriff’s Station covered in blood. She claimed to have discovered LaNell’s body in the garage after slipping on a pool of blood. According to Austin, LaNell had a plastic bag over her head, and she allegedly saw Bonheur at the scene and fled in fear.
Detectives responded immediately, finding the body in the garage just as Austin had described. A single gunshot wound to the head, latex gloves, a bloody rug, and a suspicious breakup note painted a grim picture. The evidence, coupled with Austin’s statement, seemed to implicate Bonheur. He was arrested and spent over a month in jail while investigators built their case.
However, inconsistencies soon emerged. Bonheur had an alibi backed by surveillance footage from several auto parts stores in Los Angeles, hours away at the time of the murder. He appeared distraught when told of LaNell’s death and denied any involvement. Investigators realized that the early narrative, provided by Austin, didn’t hold up under scrutiny.
The True Relationship Between LaNell and La’Rene Austin
As detectives looked deeper, they discovered Austin’s story was full of lies. Despite claiming to be LaNell’s best friend of ten years, they had only met weeks earlier through a Craigslist personal ad. What started as a romantic relationship quickly became one-sided. LaNell wanted to remain friends, but Austin’s feelings intensified into obsession.
Austin began mimicking LaNell’s persona, allegedly impersonating her on dates with other women. She became envious of LaNell’s lifestyle and saw her as a path out of financial instability. Authorities concluded that Austin’s emotional dependency and rejection drove her to commit murder. Her fabricated story and attempt to frame Bonheur nearly succeeded.
How the Murder Was Carried Out
Investigators believe Austin shot LaNell in the head while pretending to help her with her hair. A pillow was likely used as a makeshift silencer. Austin then dragged LaNell’s body into the garage, perhaps intending to move it in the car before panicking. When she realized Bonheur might return, she staged the scene to shift suspicion onto him.
The handwritten breakup note found at the scene, which claimed LaNell was leaving Bonheur for a wealthier man, was later determined to be written by Austin. Her DNA was found on the bloody gloves and a fingerprint left on a plastic container. The mounting forensic evidence contradicted her original statement and exposed her deceit.
Arrest, Trial, and Sentencing
Once detectives identified Austin as the real killer, they learned she had fled the country. After the case aired on America’s Most Wanted, Austin was tracked down in Belize and extradited to the United States. She stood trial in 2015 for first-degree murder.
The jury found Austin guilty, and she was sentenced to two terms of 25 years to life. Today, she remains incarcerated at the California Institution for Women. Prosecutors argued that her obsession with LaNell and jealousy over her success were central motives in the crime. The court agreed that Austin had acted deliberately and deceitfully.
Aftermath and Reflections
Louis Bonheur, initially wrongfully accused, was cleared and released. Despite being placed at the center of a murder investigation and spending over a month in jail, he holds no resentment toward detectives. He later married and started a family, moving forward from a traumatic chapter that nearly destroyed his life.
Josh Mankiewicz’s Dateline report highlights the dangers of jumping to conclusions and the importance of thorough investigations. “The Breakup” reveals how personal obsession and envy can lead to tragedy—and how the truth can eventually emerge even when hidden beneath layers of lies.
NBC’s Dateline: The Breakup offers a haunting look at a woman whose compassion made her vulnerable and a case that reminds viewers of the complexity behind seemingly clear-cut crimes.
