It happened while he was working on his vehicle in the front yard of this home on South Milton Avenue just after 9:30 p.m.
It looks like the truck may have been elevated by bricks when for some reason it came crashing down trapping the victim underneath.
A family member called 911. Police got to the scene first. They say there was no car jack nearby, so it took a little bit to get the man free.
Officers tried to give him CPR. When the fire department arrived, they also tried to resuscitate him.
He has been taken to a local hospital but his injuries at this time are still unknown.
Police say they're still looking into how this accident happened.
