A 63-year-old grandmother was killed and five others were injured, including three of the woman's grandchildren, Saturday afternoon when a car collided with several other vehicles and struck an apartment building in Valley Glen, officials said.
The crash occurred about 4:10 p.m. in the 12700 block of Vanowen Street, when a white 2011 BMW attempted to pass a silver Ford Mustang that was traveling westbound, according to Detective Bill Bustos of the Los Angeles Police Department.
The BMW clipped the Mustang, whose driver lost control of the vehicle and struck a large pickup truck, causing a chain-reaction, Bustos said.
The BMW also hit a parked car before it veered off the roadway, struck four pedestrians on a sidewalk, slammed through a wrought-iron fence and came to a stop against the building, police and fire officials said.
Nine vehicles, seven of which were parked, were involved in the pileup, according to Bustos.
Five of the injured were transported to a hospital: a man, a woman and three girls, the Los Angeles Fire Department said. The male patient, described as being in his 50s, was the driver of the BMW, police said.
The Fire Department initially said the two adults and two of the girls were in critical condition, while the third girl suffered "lesser injuries." Bustos later described the injuries sustained by the children -- ages 7, 8 and 13 -- as "minor to serious." They were expected to survive.
The driver of the Mustang, a man in his 20s, declined medical care at the scene, according to officials.
The critically hurt woman later died, Bustos said. Her name was not released.
She had been walking with her three granddaughters at the time of the collision, the detective said. The girls' parents, who were walking ahead of the grandmother and children, escaped injury.
No arrests or citations were immediately announced. The drivers of the BMW and the Mustang were cooperating with investigators, according to police.
"Once we collect all the evidence and examine what we have, we will make a determination (about) what we're going to do with this case," Bustos said, adding that street racing was not believed to have been a factor. "Obviously we're going to keep in contact with the district attorney's office, the city attorney's office as the investigation progresses."
Anyone with information about the incident was asked to call the Los Angeles Police Department's Valley Traffic Division at 818-644-8000.
