A coroner has identified a bicyclist who died after being hit by a pickup truck in a Colorado canyon as a university student from Brazil.

The Boulder County Coroner's Office said Friday 19-year-old Alessandro Zarzur's death Thursday remains under investigation.

Zarzur was a student at the University of Colorado and a member of the school's triathlon team. The Boulder Daily Camera reports Zarzur died at a hospital after the accident in Sunshine Canyon northwest of Boulder.

The Colorado State Patrol says Zarzur crossed a double yellow line into oncoming traffic and fell while trying to brake. The driver and passenger in the pickup weren't hurt.

Lewis says alcohol and drugs aren't considered factors but Zarzur's speed could have been.
