Jacob Watson got the 2002 Ford F-250 truck from his grandfather.
The Make-A-Wish organization restored it for Watson after he was diagnosed with cancer.
Surveillance video showed the truck being taken from a parking lot in Bedford Park Sunday while Watson was inside the new Wintrust Sports Complex.

"It meant so much to me," Watson said. "And I know to some people, it is just a vehicle, but to me, it was part of me."
An anonymous caller told Watson the truck was found in Englewood and towed to an impound lot.
It's said to be in one piece, but the ignition has been damaged.
