Lucy Crable, 81, was found murdered in her Boas Street home in Susquehanna Township, Pennsylvania, on July 4, 1995. A neighbor who noticed the backyard gate open and a screen slit discovered her on the living room floor, severely beaten about the face with bruises suggesting repeated impact against the floor. A stocking belonging to Ms. Crable had been wrapped around her neck and investigators determined she had been sexually assaulted. Unlit matches were scattered around her body.

Early investigation linked this killing to a string of similar homicides in the area. Attention turned to Andrew Dillon, a parolee living about half a block away; a neighbor saw a man matching his description entering Ms. Crable’s backyard that day and later identified him in a photo lineup. After Dillon’s arrest in September 1995 on an unrelated 1990 Scranton murder, items belonging to Ms. Crable were recovered from the apartment he shared with his girlfriend, and DNA from another local victim matched Dillon.

Did anyone in the neighborhood remember seeing unusual visitors or activity around Boas Street in the days before July 4, 1995?
