A Bountiful man was killed Saturday when his ATV rolled over on top of him as he tried to load it on to a trailer, Tooele County sheriff's deputy Aaron Bird said.

The victim, 60, and his wife had recently purchased two ATVs and had finished riding around 3 p.m. near the Pony Express Trail in a popular ATV area when the accident happened, Bird said. The man apparently did not have enough momentum driving the ATV up a ramp when it rolled backward.

A firefighter tried to revive the man, whom Bird declined to identify.
