A Stockton man was fatally struck late Thursday on Highway 99 in Modesto shortly after law enforcement officers were notified that he was running in the northbound lanes.

At 11:41 p.m, officers were notified about a pedestrian who was seen running in the northbound lanes of Highway 99, south of Kansas Avenue in Modesto, according to the California Highway Patrol incident report.

The county coroner’s office identified the man as David Pina, 46, from Stockton.

After officers arrived, they located Pina lying in the first and second lanes of the highway, Officer Ming Hsu of the CHP said. Paramedics pronounced him dead at the scene.

“It is unknown how many times (Pina) was stuck as the vehicle that struck him did not stop or report this collision,” according to the incident report. “It is also unknown how many other vehicles may have struck him as he laid in the traffic lanes.”

Investigators say the vehicle that initially hit Pina was also traveling in the northbound lanes, and they are asking for help identifying the vehicle’s year, make, model and driver.
