The Boulder County Coroner’s Office on Friday publicly identified the cyclist killed in Sunshine Canyon this week as 19-year-old Alessandro Zarzur, of Sao Paulo, Brazil.

The coroner’s office announced in a news release that it has conducted an autopsy, but the cause and manner of Zarzur’s death remain under investigation.

University of Colorado spokesman Ryan Huff confirmed that Zarzur was a CU student and a member of the school’s triathlon team.

“We are saddened to hear the news of Alessandro’s passing,” Huff said in an email. “The CU family extends its deepest condolences to his family, his friends and the entire CU triathlon team.”

Zarzur died at Boulder Community Health’s Foothills Hospital on Thursday afternoon after he collided with a truck near the 2200 block of Sunshine Canyon Drive.

Colorado State Trooper Josh Lewis said Zarzur was riding eastbound on Sunshine Canyon Drive when he went straight on a right-hand curve and crossed the double yellow line into oncoming traffic, falling down while he attempted to brake.

A 28-year-old man who was driving a 2004 pickup truck westbound attempted to avoid Zarzur, but was unable to, and collided with the cyclist, Lewis said.

The driver and his passenger were not injured, Lewis said. Alcohol and drugs are not considered factors in the crash, he added, but speed on the part of Zarzur is being considered.

Lewis had no information that indicates the driver will be charged in connection with the crash.
