One person has been killed and four others injured when an SUV tumbled down a steep slope in the Hollywood Hills.

Fire Department spokesman Brian Humphrey says the passenger car went off the road just before 8 a.m. Monday in Laurel Canyon. The car plunged between 75 and 100 feet down a hillside and came to rest upside down against a carport.

Humphrey says a man in his 70s was trapped in the vehicle and died at the scene. Four others were taken to Cedars-Sinai Medical Center, including a 1-year-old boy with moderate injuries. A woman in her 30s was in grave condition.

It wasn't immediately known who was driving the vehicle or if the victims were related.
