(MCT) — LOS ANGELES — A fugitive former Los Angeles police officer wanted in connection with a deadly shooting rampage may have fled to Mexico as a massive manhunt was gearing up to capture him, according to federal court records obtained Monday by the Los Angeles Times.

The records state how authorities developed “probable cause” that Christopher Jordan Dorner, 33, was possibly trying to escape to Mexico and provide new details on his actions since he allegedly killed three people, including a police officer, in a shooting rampage that police say began Feb. 3 in Irvine.
