NEW YORK, May 25 (UPI) -- A stone-faced New York City police officer, Justin Volpe, pleaded guilty in a packed Brooklyn courtroom to sexually torturing Haitian immigrant Abner Louima with a wooden stick. The 27-year-old officer faces a possible sentence of 30 years to life in prison without parole. Brooklyn federal court Judge Eugene Nickerson will determine Volpe's sentence in about three months. Volpe, who had been under house arrest at his Staten Island home for the past three weeks during the trial, told the court ``while in the bathroom of the 70th Precinct, in the presence of another officer, I sodomized Louima.'' Volpe said he rammed the stick up Louima's rectum and after removing it shoved it in his face. He said he did not force the stick into Louima's mouth. Volpe said he assaulted Louima because he mistakenly believed the Haitian immigrant punched him outside the Brooklyn night club on Aug. 9, 1997. He said he did not see any other police officer hit Louima outside the night spot. ``I told Louima in the Mens' room if you tell anybody I will find you and I will kill you,'' Volpe said. Volpe, whose confession was made while the jury was out of the court room, was removed from court and is now in federal custody. Because prosecutors rejected a plea deal, Volpe is not expected to testify against the other four officers charged in the beating and torture of Louima. Their trial will continue, and the judge will tell the jury not to let Volpe's absence affect their deliberations. Volpe's apparent decision to plead guilty came after four officers broke the Blue-Wall of Silence and gave damaging testimony about the events in the Brooklyn station house on Aug. 9, 1997. Sgt. Kenneth Wernick testified Volpe bragged he ``took a stick and put it 5 or 6 inches up'' Louima's rectum, ``took it out and put it up to his mouth and teeth area, kind of like showing it to him.'' Another officer testified Volpe teased him by waving the excrement- soiled stick in his face as a joke. The third officer testified he saw Volpe holding Louima with his left hand and the stick in his right hand. The fourth officer testified Volpe borrowed a pair of gloves and returned them covered with blood, which DNA tests later matched with Louima. The other officer accused in the case, officer Charles Schwarz, is accused of holding Louima down while Volpe sexually tortured him, and beating him in a police car on the way to the police station. Officers Thomas Bruder and Thomas Weise are accused of joining in the beatings in the police car. Sgt. Michael Bellomo, the supervisor that night, is accused of covering up the incident.
