Lawyer: Van der Sloot to plead guilty in Peruvian woman's death January 6, 2012 -- Updated 1333 GMT (2133 HKT) NEW: Lawyer says van der Sloot will plead guilty to all charges NEW: He hopes to get leniency for a "sincere confession" Joran van der Sloot is charged with killing a young woman in Peru The victim's father has said van der Sloot has seemed "indifferent," not "remorseful" (CNN) -- In a last-minute defense strategy change, Joran van der Sloot is expected to plead guilty to all the charges against him in connection with the killing of a Peruvian woman, his lawyer told CNN Friday. The original plan going into the trial, which was set to begin Friday, was to admit to killing 21-year-old Stephany Flores, but to fight more stringent charges that could land him more time in prison, attorney Luis Jimenez said. Jimenez said the intention of the new strategy is to give a "sincere confession," which under Peruvian law can qualify him for a more lenient sentence. If van der Sloot goes forward with this approach, he could be sentenced as early as next week. The Dutch national was considered the prime suspect in the case of Alabama teenager Natalee Holloway, who vanished in 2005 while on a graduation trip to the Caribbean island of Aruba. She was last seen leaving a nightclub with van der Sloot and two other men. Van der Sloot was arrested twice but never charged in connection with Holloway's disappearance, which is still unsolved. He now stands accused of killing Flores in his Lima hotel room in May 2010. Police say he took money and bank cards from her wallet and fled to Chile, where he was arrested a few days later. Three judges will preside over van der Sloot's trial, and there is no jury. Besides the Flores murder trial, van der Sloot also faces extradition charges to the United States.
