Iowa Man Convicted in Brutal Metal-Pipe Beatings That Killed Four

Luke Truesdell has been convicted on multiple murder charges in connection with the fatal beatings of four people in a detached garage in Marion, Iowa.

Case details

A jury found Truesdell guilty on three counts of first‑degree murder and one count of second‑degree murder on Nov. 17. The attacks occurred in June 2024, when each of the four victims sustained blunt‑force trauma after being struck with a metal pipe.

Victims

  • Romondus Lamar Cooper, 44
  • Keonna Victoria Ryan, 26
  • Amanda Sue Parker, 33
  • Brett Anthony Brown, 34

Brown was taken to a hospital in critical condition and later died; the other three victims were pronounced dead at the scene.

Statements and motive

Investigators say Truesdell told police he believed the victims were involved in sex trafficking, a claim for which authorities found no supporting evidence. He also admitted to being high on methamphetamine and to having gone without sleep for two days before the attacks.

Officials noted that remarks Truesdell made about "the possibility of the crime being made into a movie" were suppressed and were not shown to jurors during the trial.

Next steps

Truesdell faces a potential life sentence at his sentencing hearing, scheduled for Feb. 27, 2026.
