Haylee Donathan Wal-Mart Surveillance Video

NEW INFORMATION--Police have discovered a surveillance tape they say may offer clues in the case of missing 4-year-old Haylee Donathan.

Haylee disappeared while on a camping trip with her mother Candace Watson and her boyfriend Robbi Potter, a convicted sex offender.

Video from a Walmart in Marion apparently shows Haylee's mother aays after the little girl was last seen by family members.

The video goes on to show a man believed to be Potter in a truck outside with a little girl.

"It's just so hard for me to believe that she would leave her in the truck. I just don't understand it," said Mary Watson, Haylee's grandmother.

The hope is that the video paired with a $10,000 reward will bring Haylee home.
