Carlos Ortiz, an associate of Aaron Hernandez who prosecutors believe is a key witness in the killing of Odin Lloyd, has been indicted on a charge of accessory to murder after the fact.

The Associated Press reports that a Bristol County grand jury indicted Ortiz on a single count in connection with the killing of Lloyd.

Lloyd was found shot to death on June 17 in an industrial park in North Attleborough, Mass., near Hernandez's home.

Hernandez has pleaded not guilty to first-degree murder and weapons charges in Lloyd's death and is being held without bail at a county jail.

Ortiz had earlier pleaded not guilty to a gun charge. He is due in another court on Friday for a hearing on that count.

Ortiz reportedly tweaked his story on Thursday. Prosecutors said Hernandez was upset with Lloyd for talking to people with whom he'd had problems at a nightclub. Lloyd was dating the sister of Hernandez's girlfriend.

Assistant District Attorney Patrick Bomberg said Ortiz, had told authorities at least a half-dozen times that both Hernandez and Ernest Wallace got out of a car along with Lloyd at the industrial park before he heard shots ring out. Now, Bomberg said, Ortiz says he doesn't believe Wallace got out of the car.

A judge also ordered bail for Wallace, who pleaded not guilty last week on a charge of being an accessory to murder in the killing of Lloyd. The judge cited in part his lack of ties to the state and a record that included giving false names to police.
