Boston Police Commissioner Ed Davis has said investigators believe the shooting stemmed from a fight at Cure nightclub earlier that night.

Abreu and Furtado were killed when someone fired at the BMW they were in near the corner of Herald Street and Shawmut Avenue.

A third person was wounded.

Hernandez has not been charged with the double homicide but authorities have been investigating whether there is a link.

He is currently being held without bail for the murder of Odin Lloyd, 27, of Dorchester on June 17 in North Attleboro.

Police say a car found at Hernandez’s uncle’s Bristol, Conn. home, matched the description of the one they believe fled the scene after the double shooting in 2012.

Investigators are also looking at a .38-caliber pistol, seized after a June car crash from a car driven by a Bristol woman, in connection with a case involving Hernandez.

The Suffolk County District Attorney’s Office, declined to comment to the Courant, on the surveillance tape.
