Tucson Police are trying to identify a pair of suspects in an armed robbery at a Circle K.
It happened at the store on Oracle Road near Glenn on March 10.
A man in his 20s came inside and stole beer, according to a Tucson Police Facebook post . As he left the store, a security guard tried to stop him. That's when another man approached, armed with a shotgun. As the security guard left, he heard multiple shots fired.
Detectives say one of the men was involved in a theft at the same store earlier that day.
Anyone with information should call 911 immediately or 88-CRIME.
