Authorities have not said who fired the shots, but according to court documents, Ortiz told police in Florida that Wallace said it was Hernandez.
Wallace has pleaded not guilty to a charge of accessory to murder after the fact. Ortiz has pleaded not guilty to a firearm charge. Both are being held in jail without bail.
Authorities have said they haven't found the murder weapon, which they believe was a .45-caliber Glock pistol. But they recovered a magazine for .45-caliber bullets in Hernandez's Hummer as well as ammunition of the same caliber inside a condo he rented in Franklin, Mass.
Authorities also recovered a shell casing that matched those found at the homicide scene after tracking the rental car Hernandez was in the night Lloyd died.
Since then, Boston police have asked police in Hernandez's hometown of Bristol, Conn., for their help with the probe into Lloyd's homicide as well as a 2012 double homicide near a Boston nightclub. A Connecticut police lieutenant said authorities searched the home of Hernandez's uncle, seizing an SUV sought in the double killing that had been rented in Hernandez's name.
Two men died in the July 2012 shooting in Boston's South End, with witnesses reporting that gunfire came from inside a gray SUV with Rhode Island tags. Boston police haven't reported any arrests in the deaths of 29-year-old Daniel Jorge Correia de Abreu and 28-year-old Safiro Teixeira Furtado and won't comment on whether Hernandez is a suspect.
Hernandez is also facing civil litigation after a Connecticut man filed a lawsuit asserting the former player shot him in the face in February after they argued at a Miami strip club. Alexander Bradley, who says he lost an eye, told police at the time he didn't know who shot him.
In July, a judge ordered him to appear before the Fall River, Mass., grand jury hearing evidence against Hernandez in Lloyd's homicide.
