Chavira was eligible for the death penalty due to his prior conviction for murder but will instead spend his life behind bars.

He was convicted in 1988 for first-degree murder in the beating and stabbing death of his stepmother two years earlier, according to the Los Angeles County District Attorney’s Office. He was sentenced to 26 years to life in state prison and released on parole in July 2017.

De Leon left behind five sons and five grandchildren. Victim impact statements are scheduled for July 20.
