Investigators said they're searching for 30-year-old Sean Petrozzino, a quadruple amputee whose parents were found dead in an east Orange County home Tuesday.
The bodies of Nancy Petrozzino, 64, and Michael Petrozzino, 63, were found after deputies went to the house on Heming Way in the Andover Cay subdivision, south of Curry Ford Road, to do a well-being check when Nancy Petrozzino didn't show up for work, authorities said.
Their deaths have been ruled homicides and their son, Sean Petrozzino, has been named a person of interest in the case.
"We do believe he has a firearm. He's considered dangerous and they believe he is in the south Florida area," said Jane Watrel, with the Orange County Sheriff's Office.
Sean Petrozzino lost his legs and hands due to meningitis. He has two prosthetic legs, according to investigators.
Investigators said he was last seen in a 2012 red Toyota Camry with Florida tag 112VZY. They said he could be in the Jupiter or Coral Springs area.
Michael Petrozzino worked at Disney World and his wife was a second-grade teacher at Andover Lakes Elementary School.
Parents and student at the school were grieving Wednesday.
"It's just unbelievable, something you can't comprehend," said Richard Reeder, a grandparent who was at the school Wednesday.
Andover Lakes Elementary School Principal Angela Zambaux sent a message to parents that said, "I am very sad to report that we have lost second-grade teacher Mrs. Nancy Petrozzino today. She died in her home today."
"I was shocked when I found out it was her. Literally, my kids cried for hours yesterday," said neighbor Jennifer Satmaria. "My one daughter didn't even go to school today. She woke up with a migraine because she cried so much yesterday. She was just an awesome lady."
News 96.5 learned Sean Petrozzino had recently moved back to his parents' home with his Great Dane. Richard Ellwood said he met Sean Petrozzino when he and the dog moved into the house, about a week and a half ago.
"You don’t want it to be anybody. You don’t want that event to have occurred," said Ellwood. "Suddenly you open your door and there’s police tape at both ends of the street."
Former neighbor Michael Vitale spoke highly of Sean Petrozzino and was surprised by the investigation.
"There was nothing to have me doubt his integrity or honesty or anything that he might be a threat to anybody's family here," said Vitale.
On Wednesday, investigators released a photograph of Sean Petrozzino taken at an ATM at a Wells Fargo Bank in Orlando on Tuesday morning. Investigators said they wanted people to look at the physical characteristics of his hands so that someone might be able to identify him.
Sean Petrozzino's high school principal described him as a nice kid who went through a very tough time as a high school kid, after he contracted bacterial meningitis.
Neighbors said he never talked about the rare form of bacterial meningitis that ate away at his limbs. Doctors were forced to amputate both his arms and legs when he was in high school.
His south Florida high school raised money to help pay medical bills for 13 surgeries. It was his rehab that brought his family to Orlando.
Sean Petrozzino bought his own home in 2006. Court records show the bank foreclosed on the home in 2012 because he stopped paying the $1,300 monthly mortgage.
Bank records show Sean Petrozzino owed $200,000 on the east Orange County home, where the mortgage was $1,300 a month.
Anyone with information about his whereabouts is asked to call Crimeline.
