A Texas woman and her daughter were killed and another daughter seriously injured Thursday when their pickup truck flipped off a freeway overpass and fell 30 feet.

Killed in the accident were:Fannie Henrey, 87, from Hearn, Texas.

Francis Henrey, 57, from San Marcos, Calif.

The accident occurred about 11 a.m. Thursday at the 4700 South interchange of the western portion of I-215. Utah Highway Patrol investigators said Amy Orgill, 37, of Kearns, was traveling on the cloverleaf onramp to enter northbound I-215 when she apparently lost control of the vehicle on the icy road and "shot across three lanes."

Orgill's vehicle began to go into a spin and was hit by a pickup truck driven by Mary Kushner, 52, of Salt Lake County. The impact spun Orgill's vehicle around a jersey barrier. UHP trooper Glen Hill said Kushner also lost control after the collision and hit a concrete barrier.

"It (the truck) just kind of drove right up the wall," he said.

The truck then catapulted, flipped in midair and fell about 30 feet off the overpass. It landed on its top on 4700 South, narrowly missing another vehicle below, Hill said. Emergency workers had to extricate the victims from both vehicles.

Fannie Henrey and Francis Henrey were dead at the scene. They were in town visiting relatives for the holidays. Kushner was taken to University Hospital, where she was in serious condition Thursday with chest and abdominal injuries, a spokesman said. She was upgraded to fair condition Friday morning. Orgill was treated for injuries at Pioneer Valley Hospital and later released.

The accident is still under investigation.
