The man believed responsible for a shooting rampage at a Montreal college expressed anger, hatred, despair and violent tendencies in blog postings before he killed one person and wounded 19 others and was slain by police.
"Anger and hatred simmers within me," said a caption below a picture of a grimacing Kimveer Gill.
The gunman who opened fire at Dawson College on Wednesday was Gill, 25, of Laval, Quebec, near Montreal, a police official said Thursday, speaking on condition of anonymity because authorities were not ready to announce it publicly yet. Montreal-area media also identified the gunman as Gill.
He wrote that he hates jocks, preppies, country music and hip-hop.
"Work sucks ... school sucks ... life sucks ... what else can I say? ... Life is a video game; you've got to die sometime," he added.
Meanwhile a woman who says she was Gill's mother says he was "a good man." The woman answered the phone at Gill's home. She wouldn't give her name but said Gill was her son. She insisted Gill was a good man, and that a reporter could "ask the neighbors."
Six shooting victims remained in critical condition, including two in extremely critical condition.
"Shaky. Everyone's shaky," student Marianna Rekkab, who knows some of the victims, told CBS News correspondent Randall Pinkston Thursday morning.
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.
The unnamed police official also said police had searched Gill's home.
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."
In postings on a Web site called VampireFreaks.com, blog entries in Gill's name show more than 50 photos depicting the young man in various poses holding a rifle and donning a black trench coat and combat boots.
One photo has a tombstone with his name printed on it and the epitaph: "Lived fast died young. Left a mangled corpse."
The last of six journal entries Wednesday was posted at 10:41 a.m. on Wednesday, about two hours before the gunmen was shot to death at Dawson.
He said on the site that he was drinking whiskey in the morning and described his mood the night before as "crazy" and "postal."
He said on the site that he liked to play "Super Columbine Massacre," an Internet-based computer game that simulates the April 20, 1999, shootings at the Colorado high school by two of its students that left 13 people dead.
"His name is Trench. you will come to know him as the Angel of Death," he wrote on his vampirefreaks.com profile. "He is not a people person. He has met a handful of people in his life who are decent. But he finds the vast majority to be worthless, no good, conniving, betraying, lying, deceptive."
Below a picture of Gill aiming the barrel of a gun at the camera there's the inscription: "I think I have an obsession with guns ... muahahaha."
He wrote that he is 6-foot-1, was born in Montreal and is of Indian heritage. He said his weakness is laziness and that he fears nothing. Responding to the question, "How do you want to die?" Gill replied "like Romeo and Juliet — or in a hail of gunfire."
In another posting he wrote: "Stop Bullying. It's not only the bully's fault you know!! It's the teachers and principals fault for turning a blind eye, just cuz it's not their job. ... It's the police's fault for not doing anything when people complain."
In another he wrote "stop making fun of each other because of the clothes you wear, or the way people talk or act, or any other reasons you make fun of each other. It's all the jocks' fault."
Gill 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. Gill 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."
A neighbor who lives across the street from Gill 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 changed in appearance in recent months when he "started wearing a mohawk and black clothes."
A 23-year-old man and a 12-year-old girl accused in a triple murder in Medicine Hat, Alberta, earlier this year also had profiles on vampirefreaks.com.
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.
Witnesses said Gill started shooting outside the college, then entered the second-floor cafeteria and opened fire without uttering a word. At times, he hid behind vending machines before emerging to take aim — at one point at a teenager who tried to photograph him with his cell phone.
Police dismissed suggestions that terrorism played a role in the lunch-hour attack.
The gunman opened fire haphazardly at no target in particular, until he saw the police and took aim at them, Delorme said.
"We heard shootings and all I can remember is everybody going down. I can't explain it," a woman student told CBS News.
Police hid behind a wall as they exchanged fire with the gunman, whose back was against a vending machine, said student Andrea Barone, who was in the cafeteria. He said the officers proceeded cautiously because many students were trapped around the assailant, who yelled "Get back! Get back!" every time an officer tried to move closer.
Eventually, Barone said, the gunman went down in a hail of gunfire.
Although they initially suggested the gunman had killed himself, Delorme said later that "based on current information, the suspect was killed by police."
