Nancy Dolores Petrozzino, 64, was found dead from fatal gunshot wounds in her Orlando home on November 4, 2014. Her husband, Michael Petrozzino, 63, was also found dead at the scene from gunshot wounds. Their bodies were discovered after Nancy failed to report to her job as a second-grade teacher at Andover Elementary School, and the Orange County Sheriff’s Office opened an immediate investigation.

Authorities identified the couple’s son, Sean Petrozzino, 30, as the primary person of interest. Sean is a quadruple amputee who lost his hands and feet to bacterial meningitis as a teenager. He had recently moved back in with his parents after financial problems and the end of his marriage. Surveillance showed him at a Wells Fargo ATM on the morning of the killings, and he was last seen driving his father’s red Toyota Camry. Despite his physical limitations, investigators believed he was armed and dangerous and conducted a wide search.

Friends said Sean’s behavior changed after his marriage ended, and his mental state was questioned in the aftermath. The investigation involved multiple law enforcement agencies. Does anyone have information about Sean’s whereabouts that morning or about the red Toyota Camry?
