[+] EnlargeAP Photo/Jonathan WiggsAaron Hernandez has been indicted on murder charges in a 2012 double slaying in Boston.
Boston police spokeswoman Neva Coakley confirmed the indictment Thursday. Hernandez is already being held without bail after pleading not guilty to murder in the unrelated death of 27-year-old Odin Lloyd last year.
In the 2012 case, victims Daniel de Abreu and Safiro Furtado were shot as they sat in a car in Boston's South End on July 16. Police have said they were shot by someone who drove up alongside in an SUV and opened fire. Boston police have written in an affidavit there is probable cause to believe Hernandez was driving a vehicle used in the shooting and "may have been the shooter.'
