The name of the man killed in an accident at his home on Roan Road Tuesday has not been released.

The 58-year-old man was working on his truck with a friend on the property in the Thunderbird Farms area southwest of Maricopa.

“At some point while the two men were working on the truck, the truck engine started and it was in reverse,” Pinal County Sheriff’s Office spokesman Mark Clark said. “The truck started to move un-piloted [and] both men tried to regain control of the truck.”

The 49-year-old friend rolled under the truck and suffered injuries to his legs, head and arms. The owner then fell under the truck, which stopped on top of him. Clark said the fatal injury was due to massive blunt force trauma.

The 49-year-old man was air-lifted to a hospital for his non-fatal injuries.

PCSO was called to the scene around 11:15 a.m. by the victim’s wife. When detectives arrived, they found him deceased.
