A Maine man who pleaded guilty to attacking a Pittston father and daughter with a machete has been ordered to serve 50 years in prison. Justice Nancy Mills imposed the sentence on Leo Hylton after he apologized and gave an account of the May 2008 attack that laid most of the blame on his co-defendant. Mills said Hylton had given so many versions of the incident that she was torn about which one to believe. The Augusta man pleaded guilty in May to three counts of attempted murder, as well as other charges, but last month he sought unsuccessfully to withdraw the pleas. Hylton contended he pleaded guilty to shield Daniel Fortune, who’s awaiting trial. William Guerrette and his daughter, who was 10 at the time, were seriously injured.
