WHITE PLAINS, N.Y. (AP) - Federal prosecutors say a Brooklyn man has admitted being the wheelman in the killing of Florida millionaire Ben Novack Jr. at a suburban New York hotel.

Novack's widow, Narcy Novack, denies allegations that she arranged the killing.

Denis Ramirez pleaded guilty Thursday to conspiracy and domestic violence charges. He could be sentenced to life in prison.

Prosecutor Elliott Jacobson said Ramirez drove two Florida men to the Hilton hotel in Rye Brook, N.Y., on July 12, 2009, for what Ramirez believed would be an assault and robbery.

Jacobson said Narcy Novack let the two men into the Novacks' hotel room, where the men beat him to death.

Ramirez's attorney, Ismael Gonzalez, said Friday he did not know if his client would be cooperating with prosecutors.
