The mother of the Nova Scotia man who killed two sex offenders in Maine and then himself in 2006 is now fighting with the Maine Attorney General’s Office to get access to her son’s computer drive in the hope that it may provide insight into her son’s behavior, according to CBC News.

“I won’t give up until I’m satisfied that I have the information that I need to have as a mother,” Margaret Miles of Syndey, Nova Scotia, told CBC News.

Her son, Stephen Marshall, 20, used Maine’s online sex offender registry to locate his two victims, Joseph Gray, 57, of Milo and William Elliott, 24, of Corinth.

Marshall later shot himself in the head when he was approached by police while he was a passenger on a bus in Boston.

According to the story, a Maine judge has ordered the state to give Miles the computer, but that hasn’t happened, although Miles was allowed to look at some of the files this summer.

Brenda Kielty, spokeswoman for the Maine Attorney General’s Office, said she was not aware of the story and is looking into it.
