The records also show a vehicle wanted in a double killing in Boston a year before had been rented in Hernandez's name.
Hernandez has been charged with murder in the June killing of Boston semipro football player Odin Lloyd. The records say Hernandez associate Carlos Ortiz told Massachusetts investigators that another man, Ernest Wallace, said Hernandez shot Lloyd in an industrial park near Hernandez's home in North Attleborough.
The documents were filed in court by the Miramar, Fla., police department to justify a search of the home of Wallace's mother in that city.
The records also show police, while investigating Lloyd's killing, searched in Hernandez's hometown of Bristol, Conn., and found a vehicle wanted in connection with a July 2012 double homicide near a Boston nightclub
Hernandez has pleaded not guilty in Lloyd's killing. Wallace faces an accessory to murder charge in the case and has pleaded not guilty.
Prosecutors say Hernandez, Wallace and Ortiz drove with Lloyd in a rented Nissan Altima to the industrial park where Lloyd was fatally shot.
Ortiz told police that during the drive Hernandez told Lloyd that Lloyd had been "chilling" with people Hernandez had problems with, the documents say. But Ortiz told police the two men shook hands and the problem seemed smoothed over. However, the Altima soon stopped, and everyone but Ortiz got out to urinate, according to Ortiz's account.
The witness told police he then heard gunshots before Hernandez and Wallace got back into the car without Lloyd and the car sped away.
Ortiz said he couldn't see who fired the shots because it was dark.
Meanwhile, eight search warrants were unsealed in Massachusetts after news organizations sought access to them.
Records show Hernandez became "argumentative" during his first encounter with police at his home about five hours after Lloyd's body was found by a jogger. Hernandez told police he had last seen Lloyd in Boston the day before. He asked, "What's with all the questions?" and locked the door behind him.
