On the evening of April 6, 2020, 58-year-old Kenneth Knibiehly was shot and killed at his home in Albrightsville, Pennsylvania. Knibiehly was inside with his father and his girlfriend, Donna Swanson, when a knock came at the door. After briefly speaking with a man at the door, Knibiehly retrieved a handgun and a cordless phone, then returned downstairs. Swanson heard a single gunshot and found him on the floor with a fatal wound to the head; he was pronounced dead at the scene.

Investigators described a volatile love triangle involving Knibiehly, Swanson, and 66-year-old John Anthony Martocci of Roseto. Surveillance footage placed Martocci’s dark SUV near the home at the time, and he later admitted driving to the house and approaching it. A handgun recovered at Martocci’s residence matched the caliber used in the shooting. Martocci was arrested and charged in connection with the killing; investigators cited revenge and jealousy as the apparent motive.

Anyone who knew Knibiehly, Swanson, or Martocci, or who has information about the events that night, is asked to share what they know.
