Emergency personnel immediately responded to the scene, extinguishing multiple fires and assisting residents with evacuations, police said. At least a half-dozen people were on board the private jet at the time of the incident.

Federal investigators on Friday were combing a San Diego neighborhood a day after a private jet carrying a music executive and five others crashed there and are presumed dead.

“We have jet fuel all over the place,” Assistant Fire Department Chief Dan Eddy said during a news conference.
