A four-car chain-reaction collision Tuesday evening on Highway 240 sent an 18-year-old Pasco woman to the hospital Tuesday night.
Three cars were stopped about 6 p.m. in the westbound lanes of Highway 240 at Columbia Park Trail in Richland because of a separate collision, said the Washington State Patrol.
A fourth car crashed into the line of stopped cars, causing them to crash into each other.
It then fled the crash scene, WSP reported.
Jennifer B. Castroulloa, 18, of Pasco, was in the first stopped car, a 2005 Nissan Sentra.
She was taken to Kadlec Regional Medical Center in Richland with unknown injuries.
Courtney Vanwinkle, 16, of Kennewick, was in the second car, a 2005 Volkswagen Jetta. Jacquelyn S. Doyle, 43, of Pasco, was in the third car, a 2005 Toyota Prius.
