A driver accused of fatally striking a pedestrian in San Jose was captured thanks to witnesses who stopped the driver as he tried to flee the scene, officials said Sunday.

The driver, identified as 39-year-old San Jose resident Ubaldo Montaras Munoz, was being held without bail in Santa Clara County Jail on suspicion of hit-and-run and vehicular manslaughter.

The incident happened around 9:40 p.m. Saturday as Munoz drove eastbound on Capitol Expressway in his 2018 Ford pickup truck, police said.

Munoz struck an adult male pedestrian who was crossing the expressway near Silver Creek Road outside of a crosswalk or intersection, officials said.

The pedestrian was pronounced dead at the scene. He was not immediately identified.

Munoz tried to drive off after striking the man, but nearby witnesses followed him and stopped him, police said.

Investigators do not believe drugs or alcohol were factors in the incident.

The victim was the 19th pedestrian struck and killed in San Jose this year.

Anyone with information was asked to call San Jose police Detective Kevin McMillin at 408-277-4654.
