Long Islanders are demanding to know why a Nassau County cop who was found to have unlawfully shot a cab driver after a night of drinking in 2011 is still on the job and has never faced charges.

Newsday obtained the Nassau County Police Department's internal report into the affair. The report found that officer Anthony DiLeonardo recklessly escalated a roadside verbal dispute when he shot at a cab driver, Thomas Moroughan, five times, hitting him once in the arm and once in the chest in 2011.

The cab driver was arrested for assault and reckless endangerment after DiLeonardo accused him of trying to run him down with his cab. Charges were later dropped when prosecutors said there was evidence the officer had been drinking before he shot the cab driver in Huntington Station.

DiLeonardo was never charged in the case. In a statement to News 12, Nassau County Police Commissioner Thomas Dale said that "no criminal wrongdoing was found." But the police department's own internal investigation recommended disciplining DiLeonardo for what it called "11 unlawful acts" and eight department violations.

Suffolk District Attorney Thomas Spota says that the cab driver, Moroughan, refused his office's requests for information during the investigation, and that it was ultimately determined that there was insufficient evidence to present to a grand jury.

The Nassau County Police Benevolent Assocation, and both Nassau and Suffolk police departments declined to comment on the case. Nassau County Executive Ed Mangano could not be reached for comment, according to his office.
