Prosecutors: Victim bumped Hernandez before double homicide

An accidental bump at a nightclub preceded the 2012 double homicide allegedly committed by then-New England Patriots player Aaron Hernandez, an assistant district attorney alleged Wednesday during Hernandez's arraignment in the case.

Hernandez pleaded not guilty Wednesday to two counts of first-degree murder and other charges in the July 2012 killings of Daniel de Abreu and Safiro Furtado.

Hernandez, 24, who also is awaiting trial in connection with the 2013 slaying of Odin Lloyd, was indicted in the 2012 case earlier this month.

Authorities say Hernandez fatally shot de Abreu and Furtado and shot and wounded a third person after the victims had left Boston's Cure Lounge on the early morning of July 16, 2012.

At Wednesday's arraignment, Assistant Suffolk District Attorney Patrick Haggan told the court that Hernandez didn't know the victims before that night, and that Hernandez became agitated when de Abreu accidentally bumped into him while Hernandez stood at the edge of a dance floor at the lounge.
