CHP Report for the week of 9/11/19

The following incidents are submitted by the Quincy Area California Highway Patrol as a tentative summary pending the conclusion of the investigation(s).

Fatality, Sept. 2

At approximately 12:01 p.m., David Mathauser, 60, of Richvale, was driving his 2014 red Ram 2500 pickup truck westbound on Bucks Lake Road approaching 16305 Bucks Lake Road at a very high rate of speed. He had just left the Lakeshore Resort and had been involved in a hit-and-run collision there with a parked vehicle as he was leaving.

The driver had consumed part of an alcoholic beverage while at the resort, but his level of intoxication is unknown at this time. He was supposedly on his way back to his cabin (located off of Big Creek Road) to get some type of medication.


Mathauser allowed his truck to drift off the roadway and onto the north dirt shoulder. He then over-corrected to the left sending the Ram into the eastbound lane. The driver over-corrected a second time to the right. This time the vehicle went off of the north side off the roadway. The right side of the truck struck a very large fir tree. The impact deployed the side curtain airbags of the 2500 and sent the 2500 careening clockwise. The truck then struck another large fir right at the driver’s door.

The 2500 came to rest facing north on a steep downward sloping hillside, with its left side still in contact with the second fir tree.

The driver was pinned in the Ram and succumbed to his injuries on scene.

It is unknown if Mathauser was wearing his seat belt at the time of the collision.

DUI, Sept. 5

Spring Kelley Williams, 25, of Portola, was driving a 1997 Chevrolet Cavalier eastbound on Highway 70 at an unknown rate of speed, west of Plumas County Road A-24 near Nervino Airport. She was transporting one person who was seated in the right front passenger seat. It was about 9:38 p.m.


For unknown reasons Williams made an unsafe turning movement to the left. The vehicle spun in a counter clockwise direction, traveled across the westbound traffic lane and collided with a dirt drainage ditch. The car rolled over multiple times, collided with a fence and came to rest on its wheels.

The occupants climbed out of the Cavalier. The vehicle caught fire and became fully engulfed in flames. The surrounding field also caught fire.

Beckwourth Fire, USFS Fire, CHP and Plumas County Sheriff’s Office responded to the scene. The fire was controlled and extinguished. CHP and Plumas County Sheriff’s Office searched the area for the driver of the Chevrolet.

At 12:12 a.m., Williams and her passenger were located hiding in the brush, just north of the highway, about 0.75 miles west of the collision scene. Both people had sustained major injuries.

Williams was arrested for DUI and transported to Renown Regional Medical Center in Reno via CareFlight for treatment for a fractured skull. The passenger had a fractured arm and was transported to Renown Regional Medical Center by Eastern Plumas Ambulance.


Injury accident, Sept. 7

At about 10:12 a.m., Anthony Lloyd-Davies, 71, of Greenville, was driving a 2006 green Buick Terraza southbound on Highway 89, approaching Indian Falls. His rate of speed was between 50 to 55 mph.

The driver allowed the Buick to drift out of the southbound lane and into the northbound lane directly towards an approaching 2016 Subaru Impreza. The driver of the Impreza was able to swerve to the right partially onto the east shoulder and avoid being struck head-on by the Terraza.

Lloyd-Davies swerved to the right at about the same time and drove back into the southbound lane. The Buick began fishtailing while proceeding south. The driver then allowed the car to drift onto the west dirt shoulder, where the front of the vehicle struck a large boulder.

The impact deployed the Terraza’s frontal airbags and the car became airborne. The Buick rotated clockwise while rolling over counter-clockwise. The left side of the vehicle collided into a metal pole and steel cable fence protecting a drainage. Then the left side of the car impacted with the southbound lane of the highway.


The Buick came to rest facing northeast on its left side completely blocking the southbound lane and partially blocking the northbound lane of the roadway.

The driver was pinned in the vehicle and had to be extricated by fire department personnel. The extrication was extremely complicated and resulted in the highway being closed for a significant period of time.

Lloyd-Davies suffered major injures and was air lifted to Enloe Medical Center in Chico for treatment.
