Manhunt moves to Colorado with cash reward

A nationwide manhunt for fugitive sex offender now is centered in Colorado, U.S. Marshals said today.

Robbi Potter, who is believed traveling with a 3-year-old girl and her mother, was spotted at an Ampride gas station in Stratton, on Interstate 70 about 147 miles east of Denver.

"He is a convicted sex offender — the most dangerous kind — committing sex offenses against minors," said Andrew Deserto, a chief deputy U.S. Marshal in Ohio. "We want to get the little girl and want the guy caught and put him where he belongs."

Potter, 27, is wanted on both state and federal warrants for parole violations as well as escape for walking away from a halfway house for sex offenders in Mansfield, Ohio on May 28, three days after he was released from prison.

Potter is a Tier III sex offender, Ohio's most serious designation.

The U.S. Marshals Northern Ohio Fugitive Task Force is offering a $10,000 reward for
