KELSEYVILLE – Two men suffered serious injuries in a head-on collision near Kelseyville on Monday morning.

The crash took place shortly before 9 a.m. on Red Hills Road just over a mile west of the Kit's Corner intersection with Highway 29, according to California Highway Patrol Officer Adam Garcia.

Garcia said 46-year-old Michael Zappelli Jr. of Kelseyville was driving a blue 2002 C-1500 pickup westbound on Red Hills road, with 19-year-old Phillip Martin of Kelseyville coming from the opposite direction in a red 2005 Pontiac Grand Prix. Both men were traveling alone in their respective vehicles.

Preliminary evidence from the crash investigation appears to show that Zappelli's vehicle crossed into the eastbound lane and collided with Martin’s vehicle head-on, said Garcia.

Zappelli was not wearing his seatbelt and he sustained major life threatening injuries. Garcia said Zappelli was flown by REACH air ambulance to Santa Rosa Memorial Hospital.

Martin also sustained major life threatening injuries and was flown to Santa Rosa Memorial hospital

by Cal-Star air ambulance, Garcia said.

Garcia said both vehicles sustained substantial front end damage.

Alcohol is not believed to have been a factor, but Garcia said high speeds contributed to the severity of the collision.

Garcia said Officer Efrain Cortez is investigation the Monday crash.
