Two people were found dead in a Perkiomen Township home on September 24, 2023. Police discovered 53-year-old Adam Deshong and his 74-year-old mother, Wanda Deshong, on the kitchen floor with gunshot wounds; an autopsy later ruled both deaths homicides, Adam from multiple gunshot wounds and Wanda from a single gunshot to the head.

Their younger brother and son, 49-year-old Aaron Deshong, called the FBI National Threat Operation Center and told the dispatcher he might have harmed family members because he did not trust the local police. State police found Aaron in the garage on the phone with the FBI and took him into custody. Investigators recovered a Smith & Wesson .38-caliber revolver registered to Aaron in a basement closet; it contained four spent casings and two live rounds.

Aaron Deshong was charged with two counts of first-degree murder and related offenses and is being held without bail at the Montgomery County Correctional Facility. Adam Deshong, a manager for Boeing who lived in Devon, Pennsylvania, is survived by his wife and two children.
