Shaun Runyon death penalty hearing
What we know:
A psychologist testified Tuesday that Shaun Runyon experienced severe emotional disturbance when he killed three coworkers at a shared Davenport home in 2021. Dr. Tracy Hartig said Runyon suffered from military, sexual abuse, maternity, and poisoning delusions alongside past use of methamphetamine, cocaine, and marijuana.
Hartig testified that drug use combined with a delusional disorder impaired Runyon’s decision-making during the attacks. Detectives said Runyon used a baseball bat and a knife to kill the victims following an on-the-job disagreement.
Prosecutor questions delusion claims
What they’re saying:
During cross-examination, State Attorney Michael Nutter questioned whether Runyon’s condition prevented him from understanding his actions or acting purposefully.Â

“You’ve not testified that the diagnosis rendered all of his decisions irrational, correct? And you’ve not testified that the diagnosis prevented his actions from being criminal, correct?” Nutter asked.
