A search warrant indicates that Boston police have been investigating whether former New England Patriot Aaron Hernandez may have been the gunman in a 2012 double slaying.
No charges have been filed in the shooting deaths of Daniel Jorge Correia de Abreu and Safiro Teixeira Furtado in Boston's South End. Hernandez has come under scrutiny in the case since his arrest in a separate murder case in which he has pleaded not guilty.
Boston police write in the June 28 affidavit there is probable cause to believe that Hernandez was driving a vehicle used in the shooting and "may have been the shooter."
The affidavit was released Thursday in Connecticut. It was filed as police sought to search an SUV they say was involved in the 2012 shooting and was found at Hernandez's uncle's home in Bristol, Conn.
Meanwhile, Hernandez has pleaded not guilty to murder in the June shooting death of Odin Lloyd, a 27-year-old semi-professional football player who was dating the sister of Hernandez's girlfriend.
Prosecutors allege Hernandez killed Lloyd because he was upset with him for talking to some people at a nightclub with whom Hernandez had problems.
