Released evidence damning for Aaron Hernandez, but questions remain

Hernandez's attorneys must also determine a strategy for rebuking the testimony of Ortiz, who is now cooperating with law enforcement. Ortiz is described as leading police to Hernandez's "flop house" in Franklin, Mass., where police found .45 ammunition, which ballistics evidence confirmed is the type of bullet used to kill Lloyd. Even if Hernandez's attorneys can effectively portray Ortiz as selling out Hernandez to save himself -- Ortiz only faces firearm charges -- that would not debunk the underlying ammunition evidence. Police are said to have found other implicating evidence in Hernandez's apartment, including additional ammunition and a scale used to weigh drugs.
