Aaron Hernandez pleaded not guilty on Wednesday to seven charges in the 2012 shooting that killed Daniel de Abreu and Safiro Furtado.

Prosecutor Patrick Haggan said that in the months leading up the shooting, Hernandez had become increasingly convinced that people "had been testing, trying or otherwise disrespecting him when he frequented nightclubs in the area."

Haggan said that Hernandez killed them because one of the men bumped into him while dancing at a Boston nightclub causing him to spill his drink.
