Police in Toronto, Ontario (TPS) are looking for a murderer and are currently waging an all-out online effort in social media to find him. When Zabiullah Mojaddedi intervened in a street robbery last month, two men opened fire on him. One arrest has been made. Tristan Lall, 25, was on a lifetime court-ordered ban from firearms. He has been charged with first-degree murder. TPS CrimeStoppers Unit, lead by Constable Scott Mills, is spreading the word with Twitter, Facebook, and YouTube.

The murder took place in a heavily populated city park, right next to a basketball court. The video above has been posted on YouTube by TPS. In it, Detective Peter Code says, “there’s no doubt in my mind that there’s somebody out there that knows who was with Tristan Lall that evening.”
