CAMPBELL — A bicyclist riding along San Tomas Expressway in Campbell on Tuesday morning was struck and killed, according to the California Highway Patrol.

The 59-year-old Santa Clara man was riding a Motobecane bicycle southbound on San Tomas, south of Campbell Avenue, when he was hit by a gold 2004 Toyota Camry at about 11:40 a.m., according to CHP Officer DJ Sarabia.

The man — who was not immediately identified — was taken to Valley Medical Center, where he was declared dead at 12:35 p.m.

Based on a preliminary investigation, the CHP believes the driver of the Camry crossed onto the shoulder and hit the bicyclist.

A witness driver followed the Camry, which left the scene, to a Peet’s Coffee at Camden and Union avenues, Sarabia said. The suspected driver, identified as 20-year-old Melanie Souza of San Jose, called her father, who then took her back to the scene of the fatal collision.

The woman was released after being questioned while the CHP investigates the hit-and-run, Sarabia said. While charges are possible, none have been filed at this time, he said.

Alcohol is not believed to be a factor in the crash, Sarabia said.
