The California Highway Patrol is continuing to investigate Friday afternoon's fatal bike accident on Highway 29 in which the motorist left the scene.

Paul Schapiro, a former Napa County Bicycle Commuter of the Year, was killed shortly after 5:30 p.m. Friday as he rode southbound on the shoulder of Highway 29, north of Airport Boulevard.

A southbound car driven by Patricia Hill, 76, of Vallejo drifted onto the shoulder, striking Schapiro, then continued driving, the CHP said.

Law enforcement put out an alert for Hill's 2009 Honda CR-V. A Napa County sheriff's deputy pulled Hill over a short time later as she was entering American Canyon, CHP Sgt. William Bradshaw said Monday.

The CHP will be processing witness statements and is awaiting a report to learn if Hill was under the influence of drugs or alcohol or may have had medical issues, Bradshaw said. 

Schapiro, 58, died at the scene.

He was recognized in 2014 for being a devoted bicyclist who commuted 6.5 miles daily from his home in American Canyon to his job in south Napa.
