LAKE COUNTY, Calif. – The California Highway Patrol on Saturday released a report on a crash that claimed the life of a pedestrian on Friday night.

The CHP’s Clear Lake Area office said its officers were dispatched to a traffic collision with an ambulance responding for a pedestrian hit by a vehicle on Highway 20, west of Howard Avenue in Nice.

CHP Officer Corey Burgess was first to arrive on scene and located an unresponsive adult female lying in the roadway, officials said.

Officer Burgess immediately began life saving efforts, however the female succumbed to her injuries at the scene, according to the report.

The identity of the pedestrian, a 23-year-old female from Antioch, is being withheld until next of kin notifications have been made, the CHP said.

The CHP said preliminary investigations have determined the pedestrian was crossing Highway 20 from south to north, within a crosswalk at Howard Avenue.

Brannon Keller, 64, of Clearlake was driving a gray 2012 Honda Ridgeline westbound on Highway 20, approaching the crosswalk. 

For reasons under investigation, the CHP said Keller did not stop or take evasive maneuvers before the collision. 

After the crash, Keller immediately stopped his vehicle and called 911 to report the collision, the CHP said. 

Officials said Keller remained on scene and cooperated with investigating officers. 

Keller was not under the influence of drugs or alcohol and was released from the scene, according to the report.

The CHP said it is unknown if the pedestrian was under the influence of drugs or alcohol at the time of the collision.

The CHP is continuing its investigation of the crash. 

Anyone with information or knowledge of the incident is asked to contact the Clear Lake CHP Office at 707-281-5200.
