MONTREAL -- A man with a black trench coat whose shooting rampage in a Montreal college killed one person and wounded 19 others before he was slain by police said on a blog in his name that he liked to play a role-playing Internet game about the Columbine shootings.

The gunman who opened fire at Dawson College on Wednesday was Kimveer Gill, 25, of Laval, near Montreal, a police official said Thursday, speaking on condition of anonymity because authorities were not ready to announce it publicly yet. He also said police had searched Gill?s home.

Six shooting victims remained in critical condition, including two in extremely critical condition.

A woman who answered the phone at the Gill?s home and said he was her son described him as "a good man."

"Just ask anybody. Ask the neighbors. He was a good son," the woman told The Associated Press. She refused to give her name.

The woman added that police took his computer. "I don?t know what they found in the computer. They took everything," she said.

Quebec provincial police Lt. Francois Dore said authorities were waiting for autopsy results before officially identifying the killer, but "everything leads us to believe that it is, in fact, this Mr. Gill."
