The gunman killed by Vickers is identified as Michael Zehaf-Bibeau by various news agencies, quoting intelligence officials. Zehaf-Bibeau, who reportedly converted to Islam, has been brought to US agencies’ attentions, according to two American officials. One of the officials said that the man was from Quebec.
Police did not directly answer questions from reporters about the possibility that another shooter – or shooters – were still at large.
