Authorities could not confirm the identities of any of the victims or say whether the third body was that of a missing teen who lived in the home.
"Two of those bodies were associated with the airplane and then one additional body has been found."
Roseville Police spokeswoman Dee Dee Gunther says the bodies were taken to the Placer County coroner’s office in Auburn. She says neighbors are trying to cope.
"Obviously it’s a very shocking thing and something that you never expect to have happen in your own neighborhood."
Witnesses say the plane was performing stunts before plummeting into the home, something that Allen Kenitzer of the Federal Aviation Administration says it’s against the law.
"Federal Aviation Regulations strictly forbid aerobatic flying in residential areas specifically over cities, over persons, large bodies of persons."
FAA officials are still investigating the official cause of the crash.
