SANTEE, Calif.  – One person was killed and two others hurt Tuesday morning after their truck flipped on the Mission Gorge on-ramp to state Route 52 in Santee, the California Highway Patrol said.

A 33-year-old man from Escondido was driving  a GMC pick-up westbound on the freeway west of state Route 125 when he lost control of the truck, which flipped and rolled several times before landing on its roof  just before 5 a.m. A 31-year-old El Cajon man was not wearing a seat belt  and was thrown from the cab. He died at the scene. The driver and a 32-year-old woman in the truck both suffered moderate injuries and  were taken to the hospital, the Heartland Fire Department said.

The CHP arrived on-scene around 5:30 a.m. and issued a Sig Alert during the accident investigation. The Mission Gorge on-ramp to the westbound SR-52 was closed for more than two hours during the Tuesday morning commute and traffic on Highway 52 backed up as drivers slowed to see what was happening.

A 12-pack of beer was found scattered at the crash scene, but the CHP said that alcohol was not a factor in the accident..
