Authorities continued to search Thursday for a man with a hammer and a shotgun who attacked a speed enforcement vehicle on the Baltimore-Washington Parkway near BWI airport, according to a state police spokesman.
Police provided a more thorough description, saying he is a white male in his 50s or 60s with a pot belly, about 6 feet tall and 210 pounds. He was wearing glasses, a plaid flannel shirt and blue jeans, and might have been carrying a dark-colored backpack.
State police spokesman Gregory M. Shipley said investigators have no substantial leads and that there is no evidence that the attack was motivated by objections to the use of speed cameras for traffic enforcement.
The attack occurred about 11:30 a.m. Wednesday at the exit to Interstate 195, which leads to Baltimore-Washington International Thurgood Marshall Airport. State police closed the highway until about 2:45 p.m., causing substantial traffic delays.
Shipley said the man emerged from the woods and approached the State Highway Administration contractor's vehicle, which was occupied by an employee. Police said the man yelled incoherently, then hit the windshield with the hammer. He did not hit the camera mounted on the car or fire his gun.
Had the motive been an objection to speed cameras, Shipley said, "you would think the destruction would be of the speed camera and not the windshield."
Police conducted patrols through the night and checked with businesses and hotels — and are reviewing their surveillance tapes — but had no photos of the attacker. Police say the man might have parked his vehicle in a lot in the hotel district near the interchange and walked through the woods to the parkway.
"Use of a vehicle continues to be the most likely scenario," Shipley said. "Obviously, anyone could pull in and park."
Shipley said police followed a trail the man left in the woods but it ran out. In a statement released Thursday afternoon, police said they think he walked through the woods and into a parking lot in the 1300 block of Concourse Road, a business district.
Police are urging anyone who works in the area and was there between 11 a.m. and noon Wednesday to call the state police barracks in Glen Burnie at 410-761-5130.
