Baltimore County police were searching today for four assailants who forced a man and his girlfriend into the basement of the man's Rosedale-area home and fatally shot him.
Robert Stephen Collins, 28, of the 6000 block of Lanette Road, was shot once in the head yesterday afternoon, police said. He was pronounced dead at the house.
His 23-year-old companion, who was not identified, was not injured during the incident, which police said may have been drug-related.
The assailants may have escaped in either a silver Ford Taurus or Thunderbird or the dead man's 1984 cream-colored BMW with Maryland plates 278 ALT, police said.
Collins had moved into the house in the eastern part of the county 11 days ago after relocating from New York, said Sgt. Stephen Doarnberger, a police spokesman.
Police said Collins arrived home with four men shortly after 2:30 p.m. yesterday.
"Almost immediately, the four started shoving Collins and his girlfriend around, demanding drugs" and ransacking the place, Doarnberger said. "They forced both of them into the basement."
In the basement, the men covered the woman's head with a sheet and shot Collins, police said.
"We don't know whether they didn't want her to see what they wanted to do, or what," Doarnberger said.
Police said the assailants asked Collins for the highly addictive crack form of cocaine.
Doarnberger said police are investigating the relationship of the assailants and Collins and why they thought he had drugs in his home.
Because Collins' BMW wasn't parked outside or near his home, police said it was possible one of the assailants may have taken it.
Anyone with information about the shooting is asked to call police at 887-5000.
