NEW YORK (WCBS 880)  -- Former New York City police officer Hubertus Vannes is expected to plead guilty for selling guns and possessing painkillers illegally obtained.

The guns were later reported missing from the NYPD evidence room.

According to a statement put out by the Nassau Co. District Attorney's office, Vannes was arrested in November 2007 along with Anthony Vitta, 45, of East Meadow and Howard Brass, 48, of North Bellmore, as the result of an investigation into a prescription drug dealing ring. Brass, a pharmacist, has already pleaded guilty to Insurance Fraud in the Second Degree and Grand Larceny in the Third Degree, and was sentenced to eight months in jail and $1.5 million in forfeiture. Vitta’s case is pending.  He’s due back in court June 2.

Rice said that Brass would create fake patients and distribute hundreds of thousands of pills to Vitta, who is accused of selling those pills with Vannes. Vannes also admitted to selling three handguns to Vitta, who later sold two of them to undercover investigators.  Three handguns were later reported ‘missing’ from the evidence locker at the NYPD’s 110th Precinct in Queens.  Rice said investigators recovered the third handgun in Vitta’s home.
