Seal of the District Attorney of Los Angeles County

Man Charged with Murder of Good Samaritan

Posted on December 27, 2021

Los Angeles County District Attorney George Gascón announced that a man was charged Monday for the killing of Joey Manuel Casias who attempted with others to detain him after an attempted carjacking and burglary.

“This is an especially heartbreaking incident since Mr. Casias was simply acting as a good Samaritan. As we seek to ensure accountability, we also will make every possible service available to the victims and their families,” District Attorney Gascón said.

Trevor Howard Thompson, 34, of Glendora faces one felony count each of murder, attempted murder, assault with a semiautomatic firearm – a Colt 45, attempted carjacking, second-degree burglary of a vehicle, resisting executive officer, vandalism, and possession of a firearm by a felon.

On December 21, Thompson was confronted in a Covina neighborhood by citizens for reportedly breaking into a parked BMW. Thompson is charged with then attempting to carjack one of the citizen’s vehicles and then attacking another man.

 Casias, 38, intervened to try to stop the attack when Thompson allegedly shot at the man he struggled with and fatally shot Casias.

Thompson was arrested the following day after an hours-long standoff with police in which he allegedly disabled a police camera bot.

The case remains under investigation by the Covina Police Department.
