The victims in a horrific crash where a car flipped on a Marina del Rey street were identified Tuesday by the LA County Coroner.
All of the victims killed were under 20 years old, and a fourth victim remained in the hospital.
Dimnike Clemmons, 19, Anthony Sage Jr., 18, and Lavell Boyston Jr., 18, were killed when the Honda Accord they were riding in hit a curb, flipped and slammed into a tree Monday night.
New information revealed Tuesday that all four people in the car were not wearing seat belts, and speed was a factor, according to the California Highway Patrol.
