A onetime friend of Aaron Hernandez who investigators believe was with the former NFL star when he allegedly killed two men in Boston in 2012 has received immunity from the Suffolk County prosecutors who will try the case, according to a court filing.
The grant of immunity for Alexander Bradley was revealed in a legal filing in federal court in Florida, where Bradley is suing Hernandez. Bradley alleges in the lawsuit that Hernandez shot him in that state in February 2013.
In Monday's court filing, lawyers for Bradley said they provided Hernandez's civil defense counsel with a number of records, including "the Agreement for Immunity as contained in the letter between [Suffolk] Assistant [District] Attorney Patrick Haggan and attorney Robert P. Pickering, counsel for Alexander Bradley."
Suffolk District Attorney Daniel F. Conley's office has not confirmed that Bradley received immunity in connection with the July 2012 fatal shootings of Daniel de Abreu and Safiro Furtado in Boston's South End.
Prosecutors also have not stated whether Bradley will testify against Hernandez when the former New England Patriots tight end goes on trial later this year in the double slaying.
However, Conley's office has charged Hernandez with the alleged shooting of Bradley in Florida, referring to Bradley as a "percipient witness" to the Boston killings. Hernandez has pleaded not guilty to all charges.
A spokeswoman for Conley declined to comment Monday, writing in an e-mail that as "a matter of policy, we don't discuss or identify potential witnesses in any of our cases."
The filing on Monday also indicated that Bradley has testified before a Suffolk County grand jury, as well as a grand jury in Bristol County, where Hernandez was convicted in April of murdering Odin L. Loyd, a Dorchester man who had dated the sister of Hernandez's fiancee.
Hernandez is serving a life sentence for Lloyd's murder, but his lawyers are challenging the conviction. They did not respond to a request for comment on Monday.
Pickering, Bradley's criminal lawyer, also did not return messages. Bradley is currently jailed in Connecticut on unrelated gun charges.
According to prior court filings, Bradley was the passenger in Hernandez's vehicle when Hernandez pulled up alongside a car that de Abreu and Furtado were in and allegedly opened fire.
Prosecutors say Hernandez shot de Abreu and Furtado after de Abreu bumped into Hernandez at a Boston nightclub, causing the athlete to spill some of his drink.
Bradley also testified against Hernandez in the Lloyd case in Bristol County and said Hernandez handled what appeared to be a Glock firearm in a hotel room about four months before the death of Lloyd, who was killed with a .45 caliber Glock near Hernandez's North Attleborough home.
Hernandez is scheduled to stand trial in the double homicide case in December in Suffolk Superior Court.
