Charges were upgraded Thursday against the Glen Cove man accused of dismembering his neighbor.Evan Marshall, 31, is accused of breaking into 57-year-old retired teacher Denise Fox?s home and killing her. Marshall was originally going to be charged with second-degree murder. However, prosecutors say he allegedly committed the murder while committing another felony -- burglary. He was indicted on the count of first-degree murder, which carries a sentence of life without parole. Marshall was also charged with assault for an unrelated hit-and-run in Glen Cove that occurred just hours before the murder. The woman was hospitalized, but her injuries were not life-threatening. Marshall is being held at the Nassau County Jail without bond.Related Information:
