Public officials are keeping quiet about allegations that a Nassau police officer shot an unarmed man after a night of drinking.

Authorities say unarmed cab driver Thomas Moroughan was shot twice by off-duty officer Anthony DiLeonardo more than two years ago in Huntington Station.

A Nassau County Police Department Internal Affairs report obtained by Newsday says DiLeonardo and a fellow officer had been drinking. The report calls the shootings "unlawful," yet no criminal charges were ever filed against DiLeonardo.

Elected officials are keeping quiet about the report. Nassau Executive Ed Mangano, Suffolk Executive Steve Bellone, Suffolk Police Commissioner Ed Webber, Nassau Legislator Dennis Dunne and Suffolk Legislator Kate Browning have either declined to comment or have yet to respond to News 12's calls and emails.

Nassau Police Commissioner Thomas Dale has said a disciplinary investigation of DiLeonardo remains open, but says the shooting was investigated by Suffolk police and the Suffolk District Attorney's Office, and no criminal wrongdoing was found.

Suffolk District Attorney Tom Spota has said that criminal charges have not been filed because Moroughan and his girlfriend "refused to speak" to investigators.

Spota says his office contacted the Nassau County Police Department and suggested they conduct their own probe. Police internal investigators eventually recommended disciplining DiLeonardo for 11 unlawful acts and eight departmental rules violations.

Dale will not say if the officers have been disciplined within the department. Both are still on the job.
