On Thursday, a Toronto homicide detective (yes, there is murder in Canada) made an arrest in a cold case he was inspired to pick up again because of "Serial." On the very same day that Sarah Koenig dropped season two of the podcast without warning (aka Beyoncé style), the the Toronto police announced that an arrest has been made in the 2012 murder of Mike Pimintel. 

Detective Tam Bui was inspired by the "Serial" "one story, week by week" investigation of a cold murder case, so he reopened an investigation of his own. Every Saturday, he released clues and evidence from the case of the murder of Mike Pimintel, who was stabbed to death in on New Year's Eve, 2012. This crowdsourcing of a homicide case lead to hundred of new tips and leads.
