Five people were critically injured in Northridge crash Tuesday afternoon, according to the Los Angeles Fire Department.
The crash was reported about 3:50 p.m. along the 19500 block of West Roscoe Boulevard.
A silver Tacoma pickup truck and a blue sedan were involved in the crash, according to Los Angeles Police Department officials, who initially described the incident as a hit-and-run.
A mother, father and their three sons, who range in age from 18-months to 10-years-old, were all injured in the accident, according to Detective Bill Bustos.
The sixth patient was the driver of the pickup truck, according to Bustos.
Five people were described as being in critical condition by the fire department, while one was reported as being in fair condition. All six people were taken to local hospitals.
Aerial video from Sky5 showed a small child taken to an ambulance from the wreckage. It appeared that at least one of the vehicles involved had crashed into a fence along the street, aerial video showed. Both had major front-end damage.
One resident told KTLA her sister and father ran to help after witnessing the accident.
"He saw the blue truck spinning and he didn't notice the man laying on the floor at first," said Laura Ponce. "They quickly brought a towel and put it over his head. He was just saying 'I got hit, I got hit.'"
The victims of the crash were all yelling for help and many residents in the neighborhood tried to help them out of their cars, according to Ponce.
It is unclear what led up to the crash, or if one of the drivers left the scene. Bustos later indicated that speed or a left turn might have been a factor in the crash.
All the victims are expected to survive and some of the patients were upgraded from critical to serious condition later that night, according to authorities.
Friends of the family created a GoFundMe page to help pay for medical expenses.
