A group of San Diego friends’ trip to the Coachella Music and Arts Festival in Indio ended in tragedy when the vehicle they were in crashed in Banning, killing an 18-year-old woman and seriously injuring a teenage girl, California Highway Patrol officials said on Friday.

“The BMW was loaded with food, alcohol and camping gear as all three people were on their way to the Coachella Festival at the Empire Polo Grounds in Indio,” a CHP statement says.

The trio was heading east on the 10 Freeway near west Hargrave Street around 4:15 a.m. Thursday when the driver, Cesar Hernandezozuna, 21, allowed his white, 2009 BMW 328i to drift off of the roadway’s edge and onto the dirt shoulder, officials said.

The vehicle went down an embankment and stuck two trees.

“The severity of the collision severed the vehicle into two pieces, ejecting the 18-year-old, rear passenger,” the statement says. Paramedics pronounced the woman dead at the scene. She was later identified by the Riverside County Coroner’s Office as Ginevra Gallone-Latte.

Paramedics took a 16-year-old, front-seat passenger and the driver to Desert Regional Medical Center. The teenage girl sustained serious, life-threatening injuries, officials said.

It appears that the vehicle was speeding, officials said.

Although alcohol was found inside the vehicle, alcohol and drugs have been ruled out as contributing factors in the crash, the CHP said.
