The man suspected of killing at least seven women and dumping many of their remains on a remote stretch of parkway near Long Island’s Gilgo Beach in a decade-long investigation that captivated the globe is changing his plea to guilty on Wednesday — and admitting to yet another murder in which he has never been charged. Rex Heuermann, 62, had been charged in the killings of seven women, many of them sex workers, over a period of 17 years, dating back to 1993. Previously, he pleaded not guilty. Copping to the eighth, the 1996 killing of Karen Vergata, of Manhattan, is part of his plea deal, which comes with life without parole, prosecutors said. Heuermann confessed to causing Vergata’s death, but won’t face a murder charge in her case, as part of the plea deal. #gilgobeach #rexheuermann #longisland
