YORK, May 25 (UPI) -- New York City Police Officer Justin Volpe is expected to plead guilty to sexually torturing Haitian immigrant Abner Louima with a wooden stick in a police station men's room. The 27-year-old officer faces a maximum of 30 years to life in prison without parole. Brooklyn federal court Judge Eugene Nickerson will determine the sentence. Volpe is under house arrest at his Staten Island home. Because prosecutors rejected a plea deal, he 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 comes after four officers 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. Prosecutors say Volpe assaulted Louima because he mistakenly believed the Haitian immigrant punched him. 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. --=-=--
