Los Angeles: The Los Angeles Police Department’s Valley Traffic Division is investigating a fatal traffic collision that left one dead and another injured.

On June 25, 2012, around 9:37 p.m., a traffic collision occurred on Parthenia Street west of Corbin Avenue.  In the first vehicle, an 18-year-old driver and his 25-year-old sister, both from Northridge, were traveling west on Parthenia Street west of Corbin Avenue when a second vehicle traveling east on Parthenia Street veered into the westbound lane and collided with their car.

The Los Angeles City Fire Department responded to the scene and transported the drivers of both cars to a local hospital where they were treated and released for minor injuries.  The passenger in the first vehicle, identified as Griselda Sandoval, suffered fatal injuries and died at the scene.
