Police are still on the lookout for two gunmen who tried to rob an Indianapolis jewelry store Monday and threatened to kill those inside. Employees at the Jewelry Doctor in the 8500 block of East Washington Street say the men forced them and a customer to the floor, grabbed jewelry and about $2,500. That's when another employee started firing from the back of the store with a shotgun. The shots caused the gunmen to flee the scene. No one was hurt.
