Police in Howard County were looking Thursday for a gunman who tried to hold up a Jiffy Lube station in Elkridge and fired a shot at fleeing employees. He missed and no one was injured. According to police, a man entered the business on the 6200 block of Washington Blvd. about 6:45 p.m. Wednesday, pointed a gun at an employee and demanded money. The employee ran out of the building through a back door. Police said the man then entered the garage and pointed the weapon at several other employees. They fled through a rear door, and the suspect followed. As the employees ran into nearby woods, the suspect fired a single shot, police said. There were 10 employees working at the time of the robbery. Police said the suspect fled on foot without getting any money. He was described as 5 feet, 6 inches tall, with a thin build. He wore a dark, hooded sweat shirt and a black mask. Police are offering a reward of up to $500 for information leading to an arrest.
