Investigators are still trying to determine the cause of a San Diego plane crash that left at least three people dead and several others injured in the military housing neighborhood of Murphy Canyon on Thursday.

A small plane crashed into a neighborhood in Simi Valley on May 3 killing both people and a dog aboard the aircraft and igniting two homes, but no one was reported hurt on the ground despite residents being inside the residences at the time. The community is located nearly 50 miles (80 kilometers) northwest of Los Angeles.
