A 19-year-old Sandy woman was critically injured Tuesday morning when the pickup truck she was riding in collided with a garbage truck at 8313 S. Seventh East.

Police withheld the woman's name pending notification of her family.Officer Kevin Pepper said Mark Digiacomo, 20, Sandy, was driving the 1987 Toyota pickup north on Seventh East as an Ace Disposal garbage truck was backing out of an apartment complex driveway.

"The driver didn't see the garbage truck in time and couldn't veer around it," said Sandy police Sgt. Larry Davis.

The truck ran under the back of the garbage truck, then left the road and struck three cement pillars, Pepper said.

The woman was taken by helicopter to LDS Hospital where she was treated in the emergency room and then underwent surgery. Gigiacomo and the driver of the garbage truck, Bruce Turner, 25, 5965 Far Vista Drive, Taylorsville, were not injured.

Pepper said the accident is still under investigation.
