Who Is Marty Grismer & Where Is He Now? 2026 Update & Profile

Marty Grismer was identified by investigators as the man responsible for the 2013 murder of Washington middle school teacher Desiree Sunford. For more than two years after the killing, Grismer’s name was unknown to the public and to detectives working the case. When authorities finally uncovered his connection to the crime, they described him as an unlikely suspect whose obsession with another woman ultimately led to deadly violence.

The case against Grismer exposed a disturbing mix of emotional fixation, manipulation, and fantasy. Investigators concluded that Grismer became consumed with helping Paige Blades, a woman he deeply admired, and believed killing Desiree Sunford would remove the obstacle preventing Paige from being with Scott Sunford.

Marty Grismer’s Background

Compared to the other people connected to the investigation, relatively little public information has been released about Marty Grismer’s early life or upbringing. He lived in Washington state and worked with Paige Blades prior to the murder investigation.

People who knew Grismer later described him as socially awkward and emotionally dependent on Paige. Investigators came to believe that he developed an unhealthy attachment to her and interpreted their friendship as something far deeper than it was.

According to authorities, Paige herself later described Grismer as someone who “worshipped the ground” she walked on. Investigators believed that obsession became the driving force behind the murder.

The Murder of Desiree Sunford

On April 7, 2013, Desiree Sunford was found dead inside her Yakima County home after being shot seven times, including multiple shots to the head. The brutal nature of the killing immediately convinced investigators that the attack had been personal and deliberate.

At the time, suspicion focused heavily on Desiree’s husband Scott Sunford and Paige Blades after investigators uncovered their complicated romantic relationship. However, detectives lacked the evidence needed to bring charges against either of them.

For years, the case remained stalled. Authorities believed they were dealing with someone close to Desiree, but they could not identify the killer or prove who carried out the attack.

How Marty Grismer Became a Suspect

The investigation changed dramatically in 2015 when detectives received an anonymous tip identifying Marty Grismer as the killer. Authorities later traced the call back to Paige Blades.

Paige then told investigators that Grismer had confessed to murdering Desiree because he believed it would help Paige and Scott be together. According to detectives, Paige portrayed Grismer as a devoted admirer willing to do anything for her approval.

Investigators began examining Grismer’s movements, relationships, and possible access to weapons. The deeper they looked, the more suspicious the evidence became.

The Gun That Broke the Case

One of the most important breakthroughs came when Grismer’s employer contacted authorities after discovering pieces of a gun hidden at the workplace.

Investigators traced the firearm to Grismer and determined through ballistics testing that it matched evidence recovered from the murder scene. The discovery gave prosecutors the physical evidence they needed to connect him directly to Desiree Sunford’s killing.

Authorities arrested Grismer and charged him with first-degree murder. The case shocked many observers because Grismer had not initially appeared to have a direct connection to Desiree herself. Investigators concluded his motive centered almost entirely around Paige Blades.

The Alford Plea and Sentence

In 2017, Marty Grismer entered an Alford plea to second-degree murder. Under an Alford plea, a defendant does not formally admit guilt but acknowledges that prosecutors likely possess enough evidence to secure a conviction at trial.

By accepting the plea agreement, Grismer avoided the possibility of a first-degree murder conviction and a potentially harsher sentence. He received a 15-year prison sentence for Desiree Sunford’s murder.

Authorities stated publicly that they believed Grismer acted alone. Investigators said they found no evidence proving that Scott Sunford or Paige Blades directly participated in planning or carrying out the murder.

The Lingering Questions Surrounding the Case

Although Grismer was convicted, the case has continued to generate debate because of the complicated relationships surrounding the murder. Many people connected to Desiree believed there were still unanswered questions about the emotional dynamics between Grismer, Paige, Scott, and Desiree.

The threatening text messages exchanged between Paige and Desiree, combined with Grismer’s fixation on Paige, fueled public suspicion that the murder involved deeper manipulation than prosecutors were ultimately able to prove.

Dateline NBC’s “Deadly Entanglement” revisits those unresolved questions and examines why some people close to the case still struggle with the official conclusion that Grismer acted alone.

Where Is Marty Grismer Now?

Marty Grismer is believed to still be serving his prison sentence in Washington state for the murder of Desiree Sunford. Because he accepted a plea agreement in 2017 that carried a 15-year sentence, he remains incarcerated unless released under parole or other supervised release provisions allowed under state law.

Since his conviction, Grismer has maintained a low public profile and has not made significant public statements about the case. Unlike other figures connected to the investigation who later appeared in television interviews, Grismer has remained largely silent.

More than a decade after Desiree Sunford’s murder, Marty Grismer remains permanently tied to a case that exposed how obsession and emotional dependency can escalate into lethal violence. For Desiree’s loved ones, his conviction brought some measure of accountability, but not complete closure.
