Sean Petrozzino is being searched for as a person of interest in the deaths of Michael and Nancy Petrozzino
A quadruple amputee is being hunted by police after his parents were found shot dead at their home.
The bodies of 63-year-old Michael and Nancy Petrozzino, 64, were discovered on Tuesday morning after the principal of the school where Mrs Petrozzino worked called the police.
Shortly afterwards Orange County Sheriff's Office in Florida, was asking about the whereabouts of their 30-year-old son, Sean Petrozzino.
Detectives are now searching for him as a person of interest in the suspicious deaths, the Orlando Sentinel reports.
Sean is well-known in the area after making headlines for his upbeat attitude when bacterial meningitis saw him lose his hands, feet and part of his limbs as a child.
Police say they believe he is armed and may have taken his father's car - a red Toyota Camry.
But sheriff's spokeswoman Jane Watrel stressed that Sean is only a person of interest and not a suspect.
"We want him to get in here and talk to us so we can find out what happened, since he was apparently living with his parents," she said in a press conference.
He's wearing prosthetic legs and lost both of his hands during his battle with meningitis.
Homicide detectives have released a surveillance photo of Sean taken near an ATM at an undisclosed location in Orlando on Tuesday.
"Please note for identification purposes, the physical characteristics of his hands," Watrel said in a statement, adding that no other details about the picture would be released.
As authorities looked for Sean, his mother-in-law, Cathleen Horne, said he recently separated from his wife and moved in with his parents.
She said: "I've known Sean since he was 16 years old. This just seems bizarre. It seems like a bad dream."
The Petrozzino's were married for 41 years, and Nancy had been a teacher for about 40 years.
Records show a foreclosure notice was filed on Sean's former residence, and no one has lived at the address since he and his wife moved out.
