CONCORD -- An Antioch man suspected in the hit-and-run death of a woman Sunday night in Concord was picked up less than an hour after the incident on Highway 4 by the California Highway Patrol on suspicion of drunken driving.

Tyler Neal Larson, 29 was arrested Monday after he was spotted shortly after midnight standing next to his pickup truck on eastbound Highway 4 near Somersville Road in Antioch, police said Tuesday.

He had pulled over to the shoulder and was looking around, possibly inspecting damage to his vehicle, said CHP Officer Jonathan Fransen.

The incident occurred less than an hour after he allegedly struck a 46-year-old woman on Willow Pass near Fifth Street in downtown Concord, Fransen said.

The victim, Yolanda Tiscareno, had been walking on a sidewalk and was killed instantly after being hit by the truck at about 11:45 p.m., police said.

The CHP contacted Concord police, and investigators studied damage to the front end of Larson's truck and said that it was consistent with Sunday's accident. He was arrested on suspicion of felony hit-and-run, police said.

Tiscareno was homeless but working hard to change her situation, said Doug Stewart of Central County Homeless Outreach, who had known her for the past seven years.

"She had her problems, but she was always trying to turn the corner and get off the streets," Stewart said. "She never bothered anybody. She stayed with her own group."
