Angela Belisle, 35, was found dead outside her Brookes Avenue home in Burlington, Vermont, on January 3, 1981. Harsh winter conditions at first suggested she had succumbed to the cold after an apparent fall, but an autopsy showed she had been shot twice in the head and ruled her death a homicide.

Investigators say there were no signs of a struggle or robbery; her purse lay near her body, apparently untouched. Police believe the killer may have been waiting near the garage and ambushed her as she returned from grocery shopping, so authorities think she probably knew her assailant. Despite periodic reviews by Burlington and state investigators, no arrests have been announced and no suspect has been publicly identified.

Anyone who knew Angela, her routines, or saw anything unusual near Brookes Avenue on or around January 3, 1981, is asked to come forward with information.
