PASADENA -- A woman and an 11-year-old boy from the Bay Area died Tuesday when a minivan they were riding in was struck by an SUV that was fleeing police, officials said.
The fatal crash took place about 8 p.m. at the corner of Maple Street and North Marengo Avenue, Pasadena Police Chief Phillip Sanchez said.
The names of the 25-year-old woman and boy who died in the collision were not released Wednesday pending family notification, Los Angeles County Department of Coroner Lt. Larry Dietz said. They were both from Daly City, officials said Wednesday.
Two men and two women inside the SUV were treated for injuries described as moderate and arrested on suspicion of vehicular manslaughter, Pasadena police officials said in a written statement. It was not immediately clear which was accused of driving the SUV.
They were identified as Jayda Mays, 18, of Pasadena; Brittany Washington, 21, of Los Angeles; Darrell Williams, 22, of Pasadena; and Demauria Hannah, 22, of Pasadena, according to police and Los Angeles County booking records.
The pursuit began after officers attempted to stop a silver SUV for a traffic violation about a mile north of the crash scene at Marengo Avenue and Claremont Street, police said.
The suspect vehicle fled at a high rate of speed and police followed with lights and sirens, Sanchez said. "The victims' vehicle was attempting to make a left turn when it was struck," Sanchez said.
The speed at which the SUV collided with the minivan would be determined through analysis of the wreckage, Pasadena police Deputy Chief Darryl Qualls said. There were five people in the minivan, he said.
The three survivors -- a man, a woman and a young woman -- were taken to local hospitals for treatment of apparently moderate injuries, Qualls said.
The relationship between the occupants of the minivan was not immediately clear. Four people inside the SUV were treated for moderate injuries and arrested, police said.
The crash is being investigated by the Pasadena Police Department Traffic Section.
The pursuit began just under a mile away from the 1900 block of Newport Avenue, where detectives were investigating a shooting that left one man dead and another critically wounded about 9 a.m., officials said.
While no concrete link between the two incidents had been established Wednesday, Qualls said, police continued investigating to rule out any possible link between the shooting and fatal pursuit.
Though media reports indicated the silver SUV may have matched the description of one involved in the fatal shooting, Qualls said Wednesday that as far as he knew, the vehicle was being pursued only for traffic violations.
The Pasadena Police Department's policy regarding vehicle chases, "gives some latitude to the officers involved in the pursuit," Qualls said.
A pursuing officer may cancel a pursuit at his or her discretion, and ranking officers such as sergeants or lieutenants may cancel a pursuit as well if they believe it's too dangerous.
In the wake of Wednesday's double-fatal collision, department administrators would monitor the investigation.
"We're going to examine the actions of the officers. We're going to examine the actions of the suspects," Qualls said.
Upon completion of the investigation, he added, administrators will look into whether any revision to the department's pursuit policy is appropriate.
Mays, Hannah and Washington were being held in lieu of $1 million bail each pending their initial court appearances, according to county booking records. Williams was being held without bail.
