A 4-year-old boy was killed Friday morning after a garbage truck backed over him.

Thomas Breivik, 10080 S. Aberdeen Circle, was killed instantly, South Jordan Police Sgt. Lindsay Shepherd said.The Wasatch Disposal truck driver, Jason Allgood, 20, apparently did not see Breivik, Shepherd said.

"The boy was on a Big Wheel (tricycle), and it looks like he rode into the truck when it was backing up," Shepherd said.

The accident occurred about 9:50 a.m. in a cul-de-sac. The boy was killed three houses away from his home.
