The Alameda County Coroner's Bureau on Tuesday confirmed the identity of the motorcyclist who died in a collision with another vehicle at a prominent intersection in Livermore last week.

Rachel Gray, 49, of San Leandro died at the scene of the crash on Sept. 21, according to authorities.

Livermore police said on Tuesday that the fatal collision remains under investigation.

The incident occurred just before 5:30 a.m. Sept. 21 when Gray's motorcycle was struck by another vehicle at Isabel Avenue and Airway Boulevard in Livermore, according to police. The other driver, whose name has not been revealed publicly, remained at the scene and cooperated with officers, police said.

Additional details about the circumstances and cause of the crash have not been released to date.

The investigation into the crash, as well as the cleanup of debris, led to the intersection being closed for nearly six hours during and through the morning commute that day.

Investigators ask anyone who may have witnessed the crash or have other information relevant to the case to contact the Livermore Police Department's non-emergency line at 925-371-4987.
