Suspected carjacker charged in killing of good Samaritan

LOS ANGELES – Prosecutors on Monday filed a murder charge against a man suspected of killing a good Samaritan who tried to detain him after an attempted carjacking and burglary near Los Angeles last week.

Joey Casias was among several residents of Covina who confronted a man who police said broke into a parked BMW and then tried to carjack another vehicle on Dec. 21.

When the carjacker tried to attack another man, Casias tried to stop him and was shot and killed, investigators said.

Police arrested Trevor Howard Thompson, 34, after an hourslong standoff.
