Police say DNA found on a half-eaten candy bar helped them zero in on a robbery suspect.

Detective Jason Simpkins says Brian D. Bass' DNA matched the sample found on the bar left on the counter at Cato Animal Hospital during a January robbery. Bass was being held in jail Friday on $50,000 bond.

Bass was on probation after he served time on a firearms possession charge. Simpkins said the state had his DNA on file.

Police say Bass is facing felony commercial burglary and theft charges. The public defender's office says Bass, 39, doesn't have an attorney yet.
