Investigators say six people aboard a private plane died when it crashed in a San Diego neighborhood in heavy fog.

The Federal Aviation Administration confirmed that there were six people aboard the 1985 Cessna 550 Citation when it plowed into the Murphy Canyon neighborhood at about 3:45 a.m. Thursday, injuring eight people on the ground and forcing about 100 people from their homes.
