Teen arrested on suspicion of DUI in crash that left 3 dead in Castaic

A teen suspected of driving under the influence was arrested Wednesday after she lost control of her car and crashed, killing the three passengers inside, according to the California Highway Patrol.

It happened around 12:30 a.m. in the area south of Parker Road, west of the 5 Freeway. 

According to the CHP, the driver of a Toyota Camry was traveling northbound on The Old Road when she lost control at the curb, smashed into the sidewalk, a tree, then a streetlight. The car then split in half and caught on fire, officials said.

The three victims, two men and a woman, were ejected from the car and pronounced dead at the scene. 

Neighbors who tried to help the driver - later identified by CHP as 19-year-old Taylor Roberson of Redlands, told FOX 11 she was understandably distraught, and that she had told them she had been fighting with her boyfriend in the car. She also said that one of the other victims was her cousin.

Once it was determined she was under the influence of alcohol, she was arrested at the hospital, authorities said. 

No other information was immediately available.
