Officials in Utah have detained a suspect believed to be involved in a stabbing that resulted in a man's death twenty years ago, a case that remained unresolved until recent advancements in forensic science prompted a new investigation.

Jason Royter was found murdered by his girlfriend on August 6, 2005, at his Salt Lake City residence. The 33-year-old had multiple stab injuries, and his demise was classified as a homicide. For nearly a decade, detectives made unsuccessful attempts to pinpoint a suspect.

The cold case was later transferred to the Salt Lake County cold case division, where investigators continued to work diligently for another ten years. Emerging technology in investigative methods eventually provided the breakthrough they needed.

Last Thursday, Mark Munoz, aged 53, was arrested by detectives from the sheriff's office on charges of murder for allegedly being responsible for Royter's death.

DNA samples gathered at the murder scene were matched to a sample identified in 2024 by the Utah Bureau of Forensic Services, according to a local CBS affiliate report, with this sample having been directly taken from Munoz.

Upon receiving confirmation of the DNA match, the detective team initiated efforts to track down Munoz. This task proved challenging due to Munoz's status as unhoused, his lack of a mobile phone, and limited connections with family or friends, as detailed in a deputy's report quoted by KUTV.

Salt Lake County Sheriff Rosie Rivera praised the determination and perseverance of the detectives, expressing hope that this arrest provides some closure to Jason Royter's family and brings clarity to the tragic events of that day.

In a media briefing held on Friday, Rivera stressed that the investigation remains active, with authorities still in pursuit of further evidence that could strengthen the case.

She acknowledged the sorrowful nature of Royter's passing and emphasized the continuing pursuit of justice for his family and loved ones.
