PORTLAND – A Canadian man accused of killing two men on Maine’s online sex offender registry appears to have visited the homes of other sex offenders during a five-hour gap between the killings, police said Monday.
Detectives trying to account for Stephen Marshall’s movements have gathered evidence that suggests he drove to homes belonging to other registered sex offenders on Easter morning, said Detective Brian Strout, a state police investigator in Bangor.
The additional information about Marshall’s travels was based on global positioning software contained on the laptop Marshall had with him, The Canadian Press reported.
State police Sgt. Glenn Lang, who heads the Maine Computer Crimes Task Force, declined to comment Monday on what information was gleaned from the laptop.
Col. Craig Poulin, the state police chief, and Maine Public Safety Commissioner Michael Cantara will brief a legislative committee on Tuesday. Until then, state police will have no additional comment, said Stephen McCausland, state police spokesman.
Investigators have said Marshall looked up at least 34 names on Maine’s online sex offender registry before killing two men early on Easter.
Marshall fatally shot himself that evening when police stopped the bus he was riding on near Boston’s South Station, investigators said.
Police have been interested in the five-hour gap between the killings of Joseph Gray, 57, at his home in Milo, and William Elliott, 24, who lived 30 miles away in Corinth. Gray was killed at 3:30 a.m.; Elliott was killed at about 8:15 a.m.
Marshall, who lived in North Sydney, a town on Nova Scotia’s Cape Breton, was visiting his father in Houlton, Maine, when the killings took place. Detectives say he stole two handguns, a rifle and his father’s truck.
The Maine Computer Crimes Task Force began examining Marshall’s laptop computer last week.
Technicians also are expected to examine two other hard drives and some floppy disks seized from Marshall’s apartment in Nova Scotia, Strout said.
