Editor's note: Nearly three weeks after this story was published, the Livermore Police Department issued a public statement acknowledging its initial finding that the cyclist was solely at fault was incorrect under local law and revised its conclusion to "a primary cause could not be found in this collision." You can see that press release in our subsequent coverage here.

Livermore police recently completed their investigation into a traffic collision on Stanley Boulevard in which a bicyclist died, determining the longtime rider was at fault in the late-December crash.

The final police report cleared the gravel truck driver who cooperated with investigators in the days following the crash after initially leaving the scene apparently not knowing he had hit the cyclist, according to police. Christine Boyle, 63, a Livermore resident and avid bike rider, died at a local hospital hours after the collision on the morning of Dec. 21.

"Boyle was determined to be at fault and there are no criminal charges pending. The driver of the truck was fully cooperative and unaware that he had collided with her," Officer Taylor Burruss told the Weekly.

According to police, Boyle was riding off the sidewalk on eastbound Stanley Boulevard just after 8 a.m. Dec. 21 to cross straight at the intersection within the crosswalk, when at the same time a gravel truck with trailer was making a right turn from Stanley toward the Isabel Avenue/Highway 84 connector.

A witness told Boyle's family that she attempted to avoid a serious collision by pushing off the truck but she fell and was run over by the tires. Boyle was treated at the scene and transported to Eden Medical Center in Castro Valley, where she died that afternoon.

Investigators determined Boyle's movement in the roadway was in violation of the California Vehicle Code, making her the at-fault party.

The trucker's identity has not been released publicly,
