Investigators are examining wreckage and damaged homes in a Southern California neighborhood where a small plane crashed after breaking up in flight, killing the pilot and four people on the ground.
The twin-engine Cessna 414A was seen coming apart Sunday afternoon over the Los Angeles suburb of Yorba Linda and falling in pieces to the ground, torching a home where four of the victims were killed.
The Orange County Sheriff's Department says victims' identities are not yet available Monday morning.
The National Transportation Safety Board has scheduled a 2 p.m. briefing about the crash.
