Toronto police have charged Shawn Poirer, 30, with second-degree murder in the death of Mike Pimentel.

Pimentel was stabbed to death early on New Year's Day in 2012 after leaving a party.

Detective Tam Bui and several others Serial fans on the Toronto police force decided sharing weekly clues to the case on Twitter would be a good way to gather new information and get people engaged in solving the crime.

The information came pouring in.

“It was actually quite remarkable to see the amount of information that flowed back to us about those items," Homicide Staff Inspector Greg McLane said at a press conference announcing the arrest.

Police say the case was solved directly as a result of online feedback.

“All of the investigators believed it was a solvable case because of the evidence collected,” Bui, the lead investigator on the case, said at a press conference in Toronto. “We just needed the help of the public to point us in the right direction and the public stepped up.”

Poirier was arrested in Calgary on a Canada-wide warrant for second-degree murder and returned to Toronto on Dec. 8 to face charges.

Pimentel's family thanked police for their work and said they were still learning to cope with their loss.

“He was an outgoing guy, very happy. He was never sad and everyone loved being around him,” Pimentel's sister Carla said. “It’s very sad, it’s heartbreaking.”
