New Jersey Man Shoots Neighbors Over Long-Running Feud Before Taking Own Life

John Adamo, 54, critically injured a married couple in Berkeley Township before a standoff with police ended in his suicide.

John Adamo, 54, shot his neighbors Tom and Jill Kwatkoski on March 10, 2025, critically injuring both before retreating to his home.
The shooting followed years of escalating tensions between the neighbors, reportedly triggered by security cameras and 'No Trespassing' signs aimed at Adamo's house.
Adamo barricaded himself in his home for two and a half hours as SWAT teams attempted to negotiate his surrender, ultimately finding him dead from a self-inflicted gunshot wound.
Authorities discovered a pressure cooker in Adamo's home, prompting an evacuation, but it was later deemed non-threatening by the bomb squad.
Neighbors described the Kwatkoskis as kind and community-focused, while Adamo was characterized as troubled, with a history of alcohol-related issues and family estrangement.
