Man Charged with Murder After Allegedly Killing Roommate in West Valley City

A somber revelation has shaken West Valley City as prosecutors have formally charged a man accused of brutally murdering his roommate. Robert Steven Decom, 41, now faces grave charges including first-degree felony murder and second-degree felony obstruction of justice, following the tragic death of 39-year-old Shane Michael McDonald.

The horrific incident came to light on February 21, 2024, when West Valley City Police responded to a welfare check at an apartment located at 3900 South and 2700 West.

Officers discovered McDonald’s lifeless body, bearing a fatal gunshot wound to the head, starkly visible near a futon in the residence.

Court documents reveal a chilling narrative pieced together by investigators. A concerned neighbor reported hearing a single gunshot emanating from Decom and McDonald's apartment around 1:00 AM on February 21.

This crucial detail aligns with the discovery of McDonald's body later that day.

The investigation quickly focused on Decom, who was the last known person to be with McDonald. Further scrutiny brought forth disturbing information: a witness informed police that Decom had allegedly confessed to a family member that he had shot and killed McDonald.

This confession, a pivotal piece of evidence, painted a grim picture of the events leading up to McDonald’s demise.

Beyond the alleged confession, police uncovered evidence suggesting Decom’s attempts to conceal the crime. Reports indicate that Decom moved McDonald’s body, manipulated the scene, and undertook efforts to clean up the apartment in a bid to obscure the murder.

These actions form the basis of the obstruction of justice charge, highlighting a deliberate attempt to impede the investigation.

The relationship between Decom and McDonald was reportedly strained, marked by previous altercations. Court records hint at a history of conflict, with Decom having allegedly threatened McDonald in the past.

While a clear motive for the alleged murder remains to be fully elucidated, the existing tension between the roommates provides a disturbing backdrop to this tragic event.

Robert Steven Decom is currently held without bail, awaiting further legal proceedings. The community of West Valley City grapples with the shock of this violent crime, as authorities continue their meticulous work to bring justice for Shane Michael McDonald.
