A four-vehicle crash occurred west of Tucson in Three Points Wednesday night, injuring three people, authorities said.
The crash appears to be the result of a motorist trying to avoid a cow on Arizona 86, said Capt. Thomas Caldwell of Three Points Fire District.
A truck and three cars were involved in the 6:40 p.m. crash.
Firefighters had to extricate the drivers out of two vehicles, Caldwell said. Drexel Heights Fire District firefighters assisted.
Both drivers were flown by a medical helicopter to University of Arizona Medical Center, Caldwell said. He said both of the adults were in stable condition with possible life-threatening injuries.
Another adult was taken by ambulance to UAMC, and that person was in stable condition with injuries considered not to be life threatening, said Caldwell.
The fourth driver did not require medical attention, he said.
The cow was struck and killed in the crash.
Arizona Department of Public Safety officers investigated the crash and reopened the highway around 9 p.m.
