The robber apparently had scratched his head on the counter’s metal appendage when he pulled the gun.
Police detectives were notified of the discovery. Police were notified by one of the cleanup technicians who showed it to them. This company is familiar with identifying and working with police.

An address for the man was found at the courthouse and the perpetrator was arrested and convicted.
