Toronto police have made an arrest in a 2012 homicide after using social media to advance their investigation.
Mike Pimentel was stabbed to death in the city's Liberty Village neighbourhood on New Year's Day in 2012.
About a year after he was killed, a Toronto homicide detective began releasing photos and clues related to the case on Twitter, in the hope that it would lead to new information.
The method was a first for the force and was inspired by the popular crime podcast "Serial," which gradually released information about a real-life U.S. murder.
On Thursday, police announced the arrest of a Calgary man, Shawn Poirier, who has been charged with second-degree murder in Pimentel's death.
Police said the use of social media was "instrumental" in identifying witnesses and gathering new evidence in the case.
