Ottawa shooting: The suspect, the victim and the sergeant-at-arms Canadian media quoted police sources as confirming this as an image of Michael Zehaf-Bibeau Continue reading the main story Canada attack How the news broke Eyewitness: 'Astonished' In pictures Latest updates Canada is in shock after a gunman killed a soldier at an Ottawa war memorial and rampaged through Canada's parliament before being shot dead. The BBC profiles the suspected gunman, the soldier who was killed, and the sergeant-at-arms who stopped the gunman. The gunman has been widely identified as 32-year-old Michael Zehaf-Bibeau. US media reported that he was a convert to Islam, while Canadian sources told local media that the government considered him a "high-risk traveller", confiscating his passport to stop him from going abroad. Court documents show Michael Zehaf-Bibeau was convicted of several petty crimes during the early 2000s, spending several days in jail. He was charged in Quebec for crimes including credit card fraud and multiple counts of drugs possession. In Vancouver in 2011 he was also charged with robbery and making threats. A psychiatric assessment at the time considered him fit to stand trial. The suspect grew up in Laval, a city north of Montreal in Quebec. Canadian media said his father, Bulgasem Zehaf, was originally from Libya and ran a cafe in Montreal. His mother, named as Susan Bibeau, worked at Canada's Immigration and Refugee Board. The pair were said to have divorced in 1999. 'Erratic behaviour' Neighbours told broadcaster CBC Michael Zehaf-Bibeau was a sweet boy, and that they were shocked by the news. Canadian newspaper the Globe and Mail spoke to Dave Bathurst, who said he became friends with the suspect after they met in a mosque three years ago. Mr Bathurst said his friend did not appear to have extremist views at first, but had displayed some "erratic" behaviour. "We were having a conversation in a kitchen, and I don't know how he worded it: he said the devil is after him," Mr Bathurst told the Globe and Mail. "I think he must have been mentally ill." They last met at a mosque six weeks ago, when Michael Zehaf-Bibeau said he wanted to "go back to Libya to study". He insisted that he was only going abroad with the intent of learning about Islam and to study Arabic, Mr Bathust added. The victim: Cpl Nathan Cirillo People placed flowers at a memorial outside Cpl Cirillo's regiment headquarters Cpl Nathan Cirillo, a soldier guarding the Ottowa war memorial, died from his injuries following the gun attack. The 25-year-old, who had a six-year-old son, grew up in the Ontario city of Hamilton. His classmates described him as "a real class clown" who "always wanted to serve his country". Friends said he had always wanted to join the military, and became a member of his local reservist regiment, the Argyll and Sutherland Highlanders, while still a student. Cpl Cirillo was a fitness instructor before he joined the military. He was also an animal lover, posting photos of his dogs on his Instagram account. "He always had a smile on his face; he was always walking around giving people handshakes," his friend Peter DiBussolo told the Ottawa Citizen. "He was an outgoing person; he knew how to have fun." His aunt, who asked not to be named, told the Globe and Mail he was "into being fit. And being a father and son". She added: "He was a wonderful young man. Not an enemy in the world." Sergeant-at-Arms Kevin Vickers Mr Vickers is in charge of parliamentary security Witnesses identified the parliamentary Sergeant-at-Arms, Kevin Vickers, as the man who shot dead the attacker. Mr Vickers, 58, took up his role in 2006 after 29 years in the Royal Canadian Mounted Police (RCMP) and a year as the head of security at the House of Commons. His role involves "safeguarding the authority of the Houses of Commons" and "the safety and security of the Parliament buildings and their occupants". At the time of Mr Vicker's appointment, he was praised for the "loyalty, distinction and honour" he had displayed in his career. In his previous role with the RCMP he led several high-profile investigations, and was involved in the development of policies reaching out to leaders in Canada's Muslim community. He also provided security for high-profile guests, including the Queen and Prince Andrew. He last made headlines in 2011 when he supported the right of Sikhs to wear ceremonial daggers in the House of Commons. After the gun attack on parliament, politician Glenn Thibeault described Mr Vickers as the "nicest guy you'll ever meet" and "our hero". Mr Vicker's brother John told BBC Radio 5live's Breakfast: "With that event unfolding, he would be the man you would want to protect you. He's just an exemplary guy and we're very, very proud of him."
