Zanco, a Waltham High senior and wrestling captain, allegedly had a classmate set up a fake drug deal so that he could get back at 21-year-old Taylor Poulin, of Newton, for ripping off his cousin for 2 ounces of marijuana. Zanco allegedly tased Poulin with a stun gun in the parking lot, before Mendes, who arrived with Poulin, fired the fatal shots.

Poulin was arrested a week after the shooting in Windham, Maine, and was charged with assault and battery with a dangerous weapon, unlicensed possession of a firearm, possession of a firearm during the commission of a felony and conspiracy to violate drug laws. He is being held without bail.
