Montreal ? A 25-year-old man who mounted a deadly shooting rampage at a downtown Montreal college had posted pictures of himself on the Internet with a rifle and said he was feeling “crazy” and “postal” and was drinking whiskey hours before the attack.

The man, identified by police as Kimveer Gill, also said on a blog that he liked to play a role-playing Internet game about the Columbine High School shootings in Colorado and wanted to die “in a hail of gunfire.”

In the end, Gill – dressed in a black trench coat like the Columbine shooters – put his own gun to his head and pulled the trigger during a shootout with officers Wednesday at Dawson College, police said.

Gill, wielding a rapid-fire rifle and two other weapons, already had wounded 20 other people by the time he took his own life. One of his victims, an 18-year-old woman, later died. Four others remained in critical condition Thursday, including three in extremely critical condition and one in a deep coma.

The Internet postings and neighbors’ accounts reveal an angry, solitary young man who lived with his mother in Laval, near Montreal. He sported a mohawk, dressed in black and was filled with hatred for everyone from jocks to preppies and everything from country music to hip-hop. He once worked for a carpet company and more recently an auto parts business.

“Work sucks : school sucks : life sucks : what else can I say? : Life is a video game you’ve got to die sometime,” he wrote in his profile for a Web site called vampirefreaks.com.

Authorities searched Gill’s home Wednesday evening and seized his computer and other belongings.

Students embrace Thursday in front of the gates of Dawson College in Montreal. Police identified Kimveer Gill, 25, as the man who went on a shooting rampage Wednesday that killed one person and wounded 19 others before he reportedly shot himself.

“I don’t know what they found in the computer,” said a woman who answered the phone at Gill’s home and said she was his mother. “They took everything.”

She described her son as “a good man.”

“Just ask anybody. Ask the neighbors. He was a good son,” the woman said. She refused to give her name.

A neighbor across the street said he was a loner.

“There were never any friends,” Louise Leykauf said. “He kept to himself. He always wore dark clothing.”

Another neighbor, Mariola Trutschnigg, said she noticed a change in his appearance in recent months when he “started wearing a mohawk and black clothes.”

In postings on vampirefreaks.com, blogs in Gill’s name show more than 50 photos depicting the young man in various poses holding a rifle or a knife and wearing a black trench coat and combat boots.

The last of six journal entries Wednesday was posted at 10:41 a.m., about two hours before Gill died at Dawson.

Gill repeatedly said on his blogs that he loved black trench coats. He wore a black trench coat during the shooting and opened fire in the cafeteria just as Columbine students Dylan Klebold and Eric Harris did in 1999.

He also maintained an online blog, similar to Klebold and Harris, devoted to Goth culture, heavy metal music such as Marilyn Manson, guns and journal entries expressing hatred against authority figures and “society.”

He said he liked to play “Super Columbine Massacre,” an Internet-based computer game that simulates the April 20, 1999, shootings at the Colorado high school when Klebold and Harris killed 13 people and then themselves.

Montreal Police Chief Yvan Delorme said the lessons learned from other mass shootings had taught police to try to stop such assaults as quickly as possible.

“Before our technique was to establish a perimeter around the place and wait for the SWAT team. Now the first police officers go right inside. The way they acted saved lives,” he said.

Delorme said some officers were at the school on an unrelated matter when the shooting began and reinforcements were sent in.

Witnesses said Gill started shooting outside the college, then entered the second-floor cafeteria and opened fire without uttering a word. Anastasia DeSousa, 18, of Montreal was killed.

Police initially said Gill shot himself, but later Wednesday they said they thought officers killed Gill during an exchange of fire. On Thursday, however, Francois Dore of the Quebec provincial police said “preliminary results of the autopsy showed that he died of self-inflicted wounds.” Dore said police shot Gill in the arm before he turned his gun on himself.
