LOS ANGELES—Officials are expanding their search to Mexico for a man wanted for murdering police officers in Los Angeles.
According to federal court documents, Dorner is being charged with fleeing to avoid prosecution, stating there was reason to believe he had already crossed the border into the neighboring country.
Dorner is suspected in the shooting deaths of three people in southern California.
Monday, prosecutors filed a murder charge against Dorner in the shooting death of Michael Crain, a Riverside police officer.
Dorner is also wanted in connection with the murders of the daughter of a former police department captain and her fiancé.
However, charges have not been filed in that case yet.
