Cosmo DiNardo seemed to have every opportunity in life. He came from a wealthy family, was athletic and well liked and had aspirations to become an orthodontist.
“Cosmo DiNardo is the kind of kid who would always say hello, and he would grab your groceries out of your hand and walk you to your car,” a neighbor said about him.
Cosmo suffered several concussions while playing football, and he also sustained a head injury in an ATV accident. Cosmo changed. He became violent, paranoid and delusional. He would sleep with a Bible on his chest in an attempt to ward off evil. His mother said at one point, he would even foam at the mouth.
Despite all this, Cosmo’s doctor believed that treatment was working and that his bipolar was in remission. The doctor removed Cosmo from all of his medication. And then Cosmo went on a killing spree.
Along with his cousin Sean Kratz, the two murdered four men in July 2017.
