In addition to blaming DiNardo and Kratz for Sturgis' death, it contends that the elder DiNardos knew their son "suffered from mental health issues, violent tendencies, and a proclivity for utilizing firearms" yet didn't prevent him from getting access to a Smith & Wesson .357 handgun — registered to Sandra DiNardo — allegedly used to kill Sturgis. The parents, the lawsuit says, created a "dangerous condition" on their expansive farm by allowing DiNardo to have access to the property and farm equipment allegedly used in the slayings or to hide the bodies.
