KUSA - The manhunt for two people connected to the killing an elderly man in Oklahoma has spread to Colorado.

Investigators believe the two men could be in a black Chevy or GMC extended-cab pickup with large tires and aluminum wheels.

There's a reward in Oklahoma for information leading to the men who investigators think have information about the shooting of an elderly man in the parking lot of a Loaf 'n Jug in Boise City, Oklahoma last Friday.
