CLEARLAKE – A Thursday morning crash involving three vehicles outside of Clearlake injured four people, officials said Friday.

The crash occurred just before 8 a.m. Thursday on Highway 53, south of Dam Road, according to Officer Steve Tanguay of the Clearlake Highway Patrol.

Marilou Domen, 37, of Clearlake was driving her 2000 Ford Focus southbound on Highway 53 south of Dam Road with a 13-year-old passenger in her vehicle, Tanguay reported.

Tanguay said Domen was driving in the righthand lane when, according to a witness, she attempted to change lanes into the fast lane, where there already was another vehicle. Domen then overcorrected and lost control of her vehicle.

The Ford Focus went to the left and entered the northbound lanes of traffic directly in front of a

2005 Toyota Prius driven by Jerrold Grayson, 69, of Saint Helena. Tanguay said the front of the Toyota struck the right side of the Ford.

After the impact, the Ford rotated around and was struck by a 2003 Mini Cooper driven northbound by Marguerite Swint, 46, of Hidden Valley Lake, Tanguay said.

Domen was transported by Cal Star helicopter to Santa Rosa Memorial Hospital for internal trauma, while Tanguay said that the juvenile passenger was transported by REACH helicopter to Santa Rosa

Memorial Hospital and then later transferred to Oakland Children’s Hospital for internal trauma.

Swint was transported to Saint Helena Hospital Clearlake by South County Fire ambulance for complaint of pain to her back and neck. Tanguay said Grayson refused medical help and was not transported.

The collision is still under investigation by Officer Efrain Cortez, Tanguay said.
