TOPPENISH, Wash. — Six people were taken to hospitals after a three-vehicle accident just north of here, the Washington State Patrol reported Sunday morning.

Three of those injured were treated and released, while the other three were transferred to hospitals out of the area. Condition reports on the most seriously injured were not available.

The State Patrol said in a news release that a BMW 325 driven by Alvino L. Leon, 29, of Mabton was southbound on State Route 22 when it collided with another southbound vehicle, a Toyota Camry driven by Marlene A. George, 58, of Toppenish.

The crash pushed the Camry into the northbound lane, where it was struck by a Dodge Caravan driven by Rosalba A. Meza, 22, of Zillah.

The crash occurred near Branch Road about 9 p.m. Saturday. It closed a portion of the highway until 1:10 a.m. Sunday, the state Department of Transportation said.

A Yakima Valley Memorial Hospital spokesman said George, Meza and a passenger in the BMW, Amada Sanchez Morales, 25, of Mattawa, were stabilized and then transferred for treatment elsewhere. The spokesman did not know where the three were taken.

A passenger in George’s vehicle, Mayola E. Tom, 28, of Yakima, was treated and released at Memorial. Another passenger in that car, Jennifer C. George, 26, of Toppenish, was treated at Toppenish Community Hospital and released.

Leon was taken to Yakima Regional Medical and Cardiac Center in Yakima, where he was treated and released.

The State Patrol said that drugs or alcohol were believed to be involved in the accident. Charges are expected to be filed pending further investigation.
