A New Jersey woman has admitted she fabricated an allegation of rape against a man who's now serving a 20-year-sentence for the alleged assault. William McCaffrey, 31, was sentenced in 2006 after Biurny Peguero Gonzalez testified that he and two other men raped her at knife point in a van parked in Upper Manhattan in September 2005. But she now says she made the whole thing up, to cover for a fight with some of her women friends. Last year, new scientific developments enabled investigators to retest the DNA from bites on Gonzalez's arm; no "Y" chromosome was found, meaning the bites could not have come from a man.
