A clerk at a Verizon Wireless store in Inver Grove Heights exchanged gunfire and wounded one of two armed robbers late this morning, reports the Star Tribune. Authorities say one of the suspects also shot his weapon but it’s unclear who fired first. The wounded suspect was hit by gunfire multiple times. The other suspect got away in a light blue minivan and remains at large. Police say the store clerk has a government-issued permit to carry a firearm.
