UPDATE: 5:03 p.m. - Police initially said the 33-year-old had succumbed to his injuries, but police Sgt. Mike Andraychak clarified Thursday afternoon that the man remains alive but is on life support.
A man died after his car rear-ended another vehicle near the University of San Francisco early this morning, a police spokesman said.
The crash was reported at 12:33 a.m. at the intersection of Fulton and Stanyan streets.
The 33-year-old victim, whose name has not yet been released, was driving west on Fulton Street when his vehicle smashed into the back of a car that was stopped at a red light at Stanyan Street, police spokesman Officer Albie Esparza said.
The impact caused the car stopped at the light to overturn, police said.
Both drivers were taken to San Francisco General Hospital, where the first driver died, Esparza said.
The driver of the car that had been rear-ended, a 27-year-old woman, was in stable condition this morning, police said.
The crash remains under investigation, Esparza said.
