UPDATE: Aaron Hernandez is Denied Bail

It's only been a day since former New England Patriots star Aaron Hernandez was charged for the murder of 27-year-old semi-pro football player Odin Lloyd.

Now the 23-year-old is being investigated for possible involvement in a drive-by shooting that left two men dead in Boston last year.

According to ABC News, the drive-by shooting, which occurred on July 15, 2012, erupted hours after witnesses say Hernandez had been involved in an altercation at a nightclub.

A Boston Police report stated that when officers responded at 2 a.m. they "located three individuals suffering from what appeared to be gunshot wounds. Two of the victims were pronounced deceased on scene."

Hernandez's alleged involvement in the 2012 shooting has been described by four sources. His attorney has yet comment to on the investigation.
