Former New England Patriots player Aaron Hernandez, currently facing charges in a Boston-area murder last week, is now being questioned in the investigation of a double murder from July 2012. Two investigators said they now believe that the man Hernandez is charged with killing may have had information about the football player’s role in the previous two killings. Those two murders happened after a fight broke out at a club in Boston’s Theater District between the two eventual victims and a group of men that included Hernandez. Hernandez has pleaded not guilty to the charges in the recent murder.
