Quebec Election Shooting: Investigators Search For Threats Through Social Media

Police work on a crime scene outside the Metropolis in Montreal on Wednesday, Sept. 5, 2012. A masked gunman wearing a blue bathrobe opened fire during a midnight victory rally for Quebec's new premier, killing one person and wounding another. The new premier, Pauline Marois of the separatist Parti Quebecois, was whisked off the stage by guards while giving her speech and uninjured. It was not clear if the gunman was trying to shoot Marois, whose party favors separation for the French-speaking province from Canada. Police identified the gunman only as a 62-year-old man, and were still questioning him Wednesday morning. (AP Photo/The Canadian Press, Sean Kilpatrick)

Authorities are sifting through social networks for past threats and clues in addition to online comments regarding last night's fatal shooting at the Parti Quebecois victory party, CBC reports.

The shooting occurred during Quebec premier-elect Pauline Marois' victory speech, just before midnight, at Montreal's Métropolis concert hall. It left one man dead, another injured, and a third man received hospital treatment for shock. Police arrested a 62-year-old suspect outside the building.

Provincial police have begun investigating a tip stating a Parti Quebecois member got a threat before the shooting, and social media users are flagging suspicious or inflammatory remarks for the Service de police de la Ville de Montréal (SPVM).

This kind of speech can make things worse, one tweet conveys in French, pointing to another Twitter user's statement.

Another references a disturbing Facebook post.

On Reddit, users have singled out two seemingly recent comments allegedly made on Facebook; one apparently threatens "enemy" separatists, while another looks as though it makes reference to an attempt on Marois' life.

The SPVM will pass submitted tips on to investigators.

While several distasteful remarks have been identified, many social media networks have seen messages of condolences for the victims, in addition to pleas for compassion and understanding.
