LINN COUNTY, Iowa (Court TV) —An Iowa man faces life in prison after a jury convicted him of murdering four people.
Luke Truesdell was convicted of three counts of first-degree murder for the June 5, 2024, deaths of Keonna Ryan, Amanda Parker and Brent Brown. The jury found him guilty of second-degree murder in the death of Romondus Cooper.

Prosecutors argued Truesdell ambushed the group inside a garage workshop, attacking them with a three-foot metal pipe and leaving behind a bloody, chaotic scene.

Linn County deputies found the bodies of Ryan, Cooper and Parker in an outbuilding. All three had severe blunt-force injuries and were pronounced dead at the scene. Brown was also found with similar injuries and later died.
Truesdell was taken into custody at the property. Investigators said he was covered in blood and hair, and that DNA recovered from the weapon connected him to all four victims.
According to court records, Truesdell allegedly made several incriminating statements to detectives at the scene, including potential motives. However, the judge ruled that jurors would not hear those remarks because he was not read his Miranda rights before the interview. The defense’s motion to suppress was partially granted in July. A request to move the trial to another county was denied twice.
During closing arguments, prosecutors told jurors that Truesdell carried out “four executions” inside the outbuilding, striking each victim with a 42-inch metal pipe in what they described as a coordinated ambush. First Assistant Linn County Attorney Monica Slaughter said surveillance video shows the victims entering the shed moments before Truesdell followed behind, and that the pipe later recovered from the scene was coated in their blood. She argued that Truesdell’s DNA on the handle, the victims’ DNA on the weapon, and his own statements to investigators form a clear and compelling picture of guilt.

The defense countered that the state’s case is built on assumptions and pressured statements, urging jurors to reject Truesdell’s alleged confession as unreliable. Defense attorney Patrick McMullen argued Truesdell was high on meth, sleep-deprived, and traumatized when detectives questioned him — conditions he said made Truesdell susceptible to suggestion. McMullen also pointed to the lack of blood on Truesdell and gaps in the surveillance coverage, arguing police could not definitively place him inside the shed during the killings.
Truesdell faces a mandatory sentence of life in prison at his sentencing hearing, which will be scheduled at a later date.
