Authorities say a 41-year-old Concord man and his 9-year-old daughter have been killed when a teenage driver behind the wheel of an SUV lost control of the vehicle and drove up on a sidewalk.

Concord police Lt. Bill Roche told the Contra Costa Times that Soliaman Nuri and his daughter, Hadessa Nuri, died after getting hit by the SUV as they rode bicycles on the sidewalk along the city’s Treat Boulevard around 9:30 a.m. Saturday.

Officials said a second daughter was also hit by the SUV and is hospitalized with minor injuries. Her name has not been released, but authorities say she is 12 years old.

The 17-year-old driver, who has not been named, was hospitalized with minor injuries.

Police said he will be arrested on suspicion of vehicular manslaughter after he is released from the hospital.

Police are investigating whether Rosen was on his cellphone when the wreck occurred, but phone records are just one investigative lead detectives were tracking, said Concord police Lt. Bill Roche.

Roche said it is common for cellphones to be involved in vehicle crashes, but declined to say if they played any role in the collision along Treat Boulevard, near Oak Grove Road. He said Rosen had been cooperative with police.

Investigators have also drawn a blood sample from the teen. Police will need to complete toxicology tests before they rule out alcohol and drugs as a factor.

Rosen’s family could not be reached Sunday.

Witnesses said the Escalade was traveling faster than the posted 45-mile per hour speed limit on Treat Boulevard before it went out of control, skipping the curb, shearing off a fire hydrant and plowing into a medical services building.

Several of the building’s brick columns were reduced to rubble, and the brick facade was broken and cracked, revealing splintered wood beneath.

Roche said it could be a week to 10 days before traffic investigators come to a conclusion about the cause of the crash.
