Overview

• 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.
