FBI agents investigating an armed robbery at a Reno bank figured they had their man when they found the 76-year-old suspect eating lunch at a nearby casino.

The agents say they asked Tommy Ray McAdoo what he does for a living.

A criminal complaint says he answered, "I used to rob banks."

McAdoo has been in and out of prison since the mid-1960s. According to court records, he said he recently moved into the local homeless shelter because he couldn't afford to pay his monthly rent.

Prosecutors say he made off with $2,731 in a paper grocery sack last week from a bank across the street from the federal courthouse where he's scheduled to appear at a preliminary hearing on Thursday.

He's charged with bank robbery with the use of a dangerous weapon — a large steak knife.
