Surveillance video shows Robertson's feet dangling, then falling through the ceiling.

After the 12-foot drop, he ran to the area where the guns are stored during the day.

"If you notice from the video there are no guns out because we put them away at night," Travelstead said. "He came to this small area and these are the only guns we leave out. He came behind the counter and took two guns out of the case."

Police say Robertson managed to pick up two guns and several magazines.

However, officers were already waiting for him outside.

Police say Robertson tried to stash the guns, but they found them and arrested him.

It turns out, this isn't his first time getting in trouble.

"I've learned after the fact that he was arrested for car robbery and was put back on the street," Travelstead said. "So he is now in my store stealing firearms that's not good for the public. We need to work on that as an organization, state, judges, and legislators and stop it. This is ridiculous."

When he was arrested police say he gave fake names, had syringes and several blue gloves on him. He's facing a number of serious charges. The store owner said Robertson caused at least $2,000 worth of damage.
