A Baltimore man who police say is responsible for six gas station and convenience store robberies in Anne Arundel County has been charged with two counts of armed robbery after an anonymous tipster gave detectives his name.
The tipster called the Northern District police station Wednesday and gave officers the name of Roy Morris Brethauer, 18, of the 1600 block of Plum St., believed at that time to have committed five robberies in the last week, said Sgt. George Johnson, who heads the county police robbery squad.
But by 9 p.m. Wednesday, a robber using similar methods struck the Amoco gas station in the 300 block of Mountain Road. Like the other holdups, the robber walked into the station, brandished a knife and threatened the cashier.
He took money from the cash register and last was seen running from the station. After investigating that robbery, Sergeant Johnson said, detectives went to Mr. Brethauer's home.
The detectives had planned to get a description of the home so they could apply for a search warrant, Sergeant Johnson said. But Mr. Brethauer came out of the house and recognized the detectives, who were sitting in an unmarked car, as police.
One of the detectives went around to the back of the house and caught Mr. Brethauer as he tried to get out the back door.
Sergeant Johnson said when Mr. Brethauer was questioned by detectives, he admitted to six robberies, including the robbery of the Amoco station, since Sept. 17.
Clerks of businesses that had been robbed identified a photo of Mr. Brethauer as the culprit among photos of other suspects, Sergeant Johnson said. Detectives got the picture from Baltimore police who had arrested Mr. Brethauer as a juvenile, he said.
Although Mr. Brethauer is charged with two counts of armed robbery, Sergeant Johnson said the remaining four charges will be presented to a grand jury.
Sergeant John said Mr. Brethauer admitted to the Sept. 17 holdups of Uncle Marvin's Oasis in the 7700 block of B&A Boulevard, and Dan's Crown gas station in the 5700 block of Ritchie Highway; the Sept. 19 robberies of Ray's Crown gas station in the 8200 block of Veteran's Highway and the Crown gas station in the 7600 block of B&A Boulevard; the Sept. 22 holdup of the Royal Farm store in the 200 block of Oak Manor Drive in Glen Burnie, and the Amoco station in Pasadena.
