A Westchester man will spend the rest of his life behind bars after being given the maximum sentence after pleading guilty to the violent murder of a Rockland County man near his Nanuet home last summer. Earlier this year, Yonkers resident Frank Keogh, who worked as a contractor in Hopewell Junction, pleaded guilty to second-degree murder in Rockland County Court after his stabbing victim, Pearl River native Eric Leopold, died from more than a dozen stab wounds outside his home.
