Former Las Vegas drug prosecutor David Schubert, who also handled the cocaine possession plea deals of Paris Hilton and Bruno Mars, was sentenced to go to jail for nine months in county jail for the drug case he is embroiled in.

Former Deputy District Attorney David Schubert made an apology to the court for what he called “a tragedy’’ on his drug case, after which he stood silently and hung his head in shame as a state court judge reproached him as “a disgrace to his oath as a prosecutor and a lawyer.’’ Clark County District Judge Carolyn Ellsworth also said that the terms of a plea deal which could have gotten David Schubert probation and a chance to clear his record were “offensive,” adding’ “I’m not going to give you the special treatment.”

The authorities busted David Schubert in March 2011 after they watched another man get out of the former prosecutor’s car, go into an apartment complex and return. Officers found Schubert in possession of a $40 crack cocaine and sequestered an unregistered 9 mm handgun from his car. David Schubert once handled Clark County’s highest-profile drug case and prosecutions as the district attorney office’s liaison to a federal drug task force.

One such case he handled was that of Paris Hilton who was apprehended by the police after a 0.8 grams of cocaine fell out of her handbag following a Las Vegas Strip traffic stop in August 2010. The 30-year-old celebrity socialite received a year of probation on misdemeanor cocaine possession and obstruction charges. Hilton successfully completed probation last fall. Another drug case of David Schubert was that of Bruno Mars, who was cleared in January of a felony cocaine possession charge after keeping his nose clean for a year and fulfilling other conditions of his plea deal. The ‘Just The Way You Are’ singer, whose real name is Peter Hernandez, acknowledged in court in February 2011 that he was in possession of 2.6 grams of cocaine after a performance at a Hard Rock Hotel & Casino nightclub.

David Schubert relinquished his job from the prosecutor’s office after his arrest and underwent two months of in-patient substance abuse counseling. The 48-year-old former prosecutor has been under an  out-patient alcohol and drug counseling program since May, and has been practicing criminal defense law in some of the same courtrooms where he was a prosecutor for ten years.

Schubert pleaded guilty to his drug case, a felony charge of unlawful possession of a controlled substance not for sale. The conviction could give a fatal blow to the law career of David Schubert, depending on a review by the State Bar of Nevada and action by the state Supreme Court. The judge has given Schubert until March 12 to surrender and begin his jail sentence.

David Schubert’s defense attorney, William Terry, said he may appeal the sentence for the drug case or ask the judge to take the rare step of setting it aside.
