The surveillance photos were taken of Robbie Potter's pickup on June 2 at a Stratton Colo., gas station, 10TV's Tanisha Mallett reported.  In the photos, a woman believed to be Potter's girlfriend, Candace Watson, was seen attempting to purchase fuel.

Authorities believe that Potter is with Watson and her 4-year-old daughter, Haylee Elizabeth Jade Donathan, but only Watson was seen in the June 2 photos.

SLIDESHOW:  Surveillance Photos

Two days before the photos were taken in Colorado, the same pickup was seen at a Marion Wal-Mart.

The child is considered to be in serious danger because Pitter is a Tier III sex offender for sex crimes against a minor.  He is wanted for a parole violation and on a federal warrant for probation violation.

On May 28, Potter fled a halfway house in Mansfield.

The pickup is a 1988 two-tone black and green Chevrolet with Ohio license plate No. ENS-9729.  The truck has orange lights along the top of the windshield visor and running boards along the sides.
