Fairfax mall slasher pleads guilty A onetime day laborer admitted in court Monday that he would creep up behind young women at Fairfax County shopping malls, slash their buttocks with a razor blade or box cutter and then disappear into the crowd. Johnny D. Guillen Pimentel, who was arrested in January 2012 in his native Peru, pleaded guilty to two counts each of malicious wounding and unlawful wounding in Fairfax County Circuit Court. He faces up to seven years in prison. He was suspected of slashing nine women in their teens or early 20s between February and June 2011 at Fair Oaks Mall, Tysons Corner Center and other locations. None of the women was seriously wounded, but the bizarre and random attacks prompted police to form a task force to track down the assailant. On Monday, he admitted to attacks on four women. As part of the plea deal, five additional charges were dropped. Neither prosecutors nor Guillen Pimentel's defense attorney gave any indication of why he carried out the attacks. His brother has told The Washington Post that Guillen Pimentel worked as a day laborer in the United States and has a young son. He said Guillen Pimentel came to the United States about a decade ago. One of Guillen Pimentel's family members who came to court Monday declined to comment. Police have said that he fled to Peru in December 2011 and was arrested there in January 2012. He is scheduled to be sentenced Sept.
