TALLAHASSEE, Fla. (AP) — A man who killed a Tampa police officer will have his death sentence reduced to life without parole.

The Florida Supreme Court ruled Thursday that a death sentence wasn’t appropriate for Humberto Delgado Jr., who fatally shot Tampa police Cpl. Mike Roberts in 2009.

Delgado had pushed a shopping cart 15 miles on his way to a veterans’ shelter when Roberts stopped to question him. Delgado ran and Roberts used a stun gun on him. Roberts was shot during a scuffle that followed.

Delgado had suffered from mental health issues for years, including psychotic episodes in which he thought police were trying to kill him.
