Murder charges have been filed against Jeb Daly, the man accused of killing his live-in girlfriend in Huntington.  Police say 30-year old Jessica Dana died by blunt force trauma to the back of her head.  Dana's body was found in a cardboard box behind the couple's home.  Daly was at first charged with improper disposal of a body and misleading police.  Daly pleaded not guilty to the murder charge Friday in Northampton District Court.  He's being held without the right to bail.
