Wassenaar is accused of violently killing Donald Lashley, Thomas Harnage, and Saul Alvarez at the Arizona State Prison Complex in April 2025. He was serving 16 life sentences at the time of the crime and is currently charged with three counts of first-degree murder and aggravated assault.

Attorney Miller says that given the evidence, and Wassenaar's extensive violent history, he believes the death penalty is "appropriate."

"The Pinal County Attorney’s Office alleges the crime meets the statutory aggravating factors necessary to impose the death penalty under Arizona law," the officials said.
