Overview
- Michael James McCormack was sentenced Monday to 75 years in prison after a jury convicted him on five counts, including felony murder and aggravated robbery.
- Charles Shay was sentenced on Sept. 10 to life without the possibility of parole plus 120 years following an August verdict on 10 counts and a habitual criminal finding based on six prior felonies.
- Court documents say surveillance video captured Shay pulling a gun, attempting to handcuff Peter Arguello, and firing three shots when the store owner resisted.
- Police reported that DNA from handcuffs recovered at the West 38th Avenue scene tied McCormack to Shay and led to McCormack’s arrest months after the 2023 killing.
- In statements at sentencing, wife Teresa Casillas said the punishment cannot restore her husband and criticized delays and expected appeals, while Chief Deputy DA Chandler Grant said the outcomes provide accountability.
