Several emergency crews responded to a five-vehicle crash with multiple injuries Thursday night on Highway 166.

Just before 8:30 p.m., Santa Barbra County Fire, along with the California Highway Patrol and AMR, responded to a call to Highway 166, west of Tepusquet Road.

According to the CHP report, Patrick Hourigan, 55, of Truckee, was driving his 2012 Infinity FX35 eastbound on at about 55 mph when he made an unsafe passing movement over double yellow lines and failed to see the four oncoming vehicles. 

Allison Starcher, 53, of Santa Monica, Kenneth Delunas, 64, of Santa Ynez, Fausto Dominguez, 52, of Sun City, and Benjamin Smith, 42, of Santa Barbara, were report traveling westbound at approximately 50 mph. 

The left front of Hourigan's car collided with the left front of Starcher's 2006 Toyota Prius, the CHP said. Hourigan continued traveling east and collided with the front of Delunas' 2004 BMW 325, the left side of Dominguez's 2016 Freightliner, then struck the left rear side of Smith's 2017 Toyota Highlander before coming to a rest.

Delunas' BMW blocked both lanes of the highway, according to the CHP, which remained closed to allow a CALSTAR helicopter to land safely and transport Starcher, who sustained major injuries, to Santa Barbara Cottage Hospital.
