Police in Orange County, Fla. are looking for a quadruple amputee who is considered a person of interest after his parents were found shot to death.

Sean Petrozzino, 30, had recently moved back in with his mother and father, Nancy and Michael Petrozzino, after separating from his wife, the Orlando Sentinel reports. Their bodies were discovered in their home Tuesday after Nancy failed to show up at work. Michael’s car, a red Toyota Camry, is also missing.

The sheriff’s office has maintained that Petrozzino is not currently a suspect, only wanted for questioning to investigate the circumstances around his parents’ shootings. But a spokesperson added that he was armed.

Petrozzino lost his hands, feet and parts of his limbs to bacterial meningitis as a teenager. It is possible for a person without hands to fire a gun, according to one prosthetics and orthotics expert who spoke to the Sentinel.
