Hunt On For Murdered Cotati Teen's White Bicycle

SONOMA COUNTY, CA – Detectives investigating the murder of 18-year-old Kirk Ryan Kimberly, the Cotati teen found last week stabbed to death and buried in a shallow grave on the Sonoma State University campus, have turned their attention to what happened to his bicycle.

Kimberly was last reported seen Oct. 17 when he left Cotati on a white bicycle to meet a friend in Rohnert Park, Cotati police said. He did not return home and stopped communication with friends and family, police said.

His body was found on the Rohnert Park campus by a landscaper around 3 p.m. Wednesday, covered by dirt and debris roughly 200 yards west of parking lot "M," and was identified using fingerprints. Sonoma County sheriff's officials said the missing teen was stabbed multiple times.

His bicycle is described as a white, men’s 2011 Cannondale Quick CX3 mountain bike. It had recently installed road tires, which have reflective material built into the sidewalls. (See photographs.)

Detectives said the killing of Kimberly "was not a random act of violence, but an isolated incident," and that the murder appears to have no link to Sonoma State.

"Thus far, detectives have found no affiliation with the homicide and Sonoma State University or its students, other than where the body was found, which was on the property in an isolated and secluded area of the campus," said Lt. Tim Duke.

The Sonoma County Sheriff's Office took over the investigation at the request of campus police.

A pathologist from the county coroner's office, an investigator with the district attorney's office and violent crimes detectives spent hours unearthing the remains on Thursday, Sonoma County Sheriff's Office spokesman Sgt. Spencer Crum said.

"There's no time restraint," Crum said.

The remains were "in the form of a body and are not just bones," he said.

Officials said they are not disclosing such details as how many or where stab wounds were on the victim or what type of weapon was used.

Anyone with information related to the Cannondale mountain bike or Kimberly's disappearance and death is asked to contact Sonoma County Sheriff’s Detective Horsman at 707-565-2185.
