SAN BERNARDINO COUNTY, Calif. – On December 29, 2022, William Shea McKay was identified as the shooter that killed Deputy Isaiah Cordero with the Riverside County Sheriff’s Department during a traffic stop in Jurupa Valley.

The San Bernardino County District Attorney’s Office prosecuted McKay, who was convicted of his third strike in November 2021. Despite our requests at that time to set bail at No Bail, his bail was reduced by the judge to $500,000.00, and his sentencing was continued. McKay posted bail in March of 2022, and unfortunately in July was granted another continuance for sentencing, which our Office also objected. Lastly, McKay failed to appear to his sentencing in October 2022 and was issued a bench warrant.

“Our Office is saddened to learn of the death of Riverside County Sheriff’s Deputy Isaiah Cordero,” says District Attorney Jason Anderson. “Our Office upheld our oath of pursuing justice by prosecuting convicted felon McKay in November of 2021, however a failure in the process to separate McKay from society and hold him accountable for his crimes has resulted in the tragic loss of a law enforcement deputy. Our prayers are with Riverside County Sheriff’s Department and particularly the family and loved ones of Deputy Isaiah Cordero, who paid the ultimate sacrifice ensuring the safety of his community.”
