Ex-Patriots tight end Aaron Hernandez, charged Thursday in the murder of semi-pro football player Odin Lloyd, 27, is also being investigated for a double murder in a drive-by shooting from nearly a year ago in Boston, law enforcement officials told NBC News. The men, Daniel Abreu and Safiro Furtado, were shot to death from an SUV after leaving a nightclub, and a third was wounded. Charges have not been filed, and no suspects have been named in connection with that case. Hernandez, who is being held in jail without bail, has pleaded not guilty to the first-degree murder charge and five gun charges in the execution-style killing earlier this month of Lloyd. Prosecutors said he had summoned two friends from out of state before driving to pick up Lloyd and carry out the killing.
