A crash involving six vehicles in the University City area early Monday left one person dead and several injured, the California Highway Patrol said.

The crash was reported shortly before 8 a.m. on the off-ramp from northbound I-5 to Genesee Avenue, said CHP Officer Michael Meza. A San Diego police officer responding to the scene performed CPR on a severely injured person, who was transported to a hospital and later died, Meza said.

The ramp was closed for more than an hour. It reopened to traffic around 9:45 a.m., Meza said.

Multiple people were transported to hospitals to be treated for injuries suffered in the crash. No information about the extent of their injuries was released.

It wasn’t clear what led to the crash. No information about the person who died was immediately released.
