Manchester man wanted for NH murders, child pornography possibly sited in Florida
A New Hampshire man wanted for killing his parents and setting their house on fire was in the Tampa Bay area, but police officials there believe he is once again on the run after stealing the car of a Florida woman he befriended.
St. Petersburg police and the U.S. Marshals Service on Tuesday said that Matthew Thomas Dion had been in the St. Petersburg area since late March 2014 and was last seen on Sept. 6.
Dion, 38, is charged with two counts of second-degree murder in the deaths of his parents, Robert and Constance Dion, whose bodies were discovered after their Manchester home caught fire and exploded in March 2014.
Investigators said both had been strangled days before the blaze. Dion is also facing child pornography charges.
Detectives from New Hampshire were in St. Petersburg, interviewing witnesses and conducting other investigations in the case, but left today, according to Mike Puetz, police spokesperson for St. Petersburg police.
Puetz said police believe Dion is driving a stolen silver 2013 Hyundai Elantra, with the Florida plate of G673WH.
"We believe that he came into St. Petersburg around March 31," said Puetz. "He was befriended by a family who allowed him to stay in their home."
Puetz said Dion became romantically involved with the woman, who lived in the home with her teenaged son.
At some point earlier this month, the woman became aware of money missing from her bank accounts, and confronted Dion, who was living under an alias.
"Before she could confront him, he got wind of the fact that he was under suspicion, so he ended up stealing her car, and abandoning the car he came to Florida with," said Puetz.
That car was recovered - initially it was towed by a private towing service, ad as abandoned car.
Police say Dion did not know the woman previously, and they are not certain of why he first fled to Florida.
"He may have had connections here that brought him back," said Puetz.
Authorities were drawn to the St. Petersburg area in their search for Dion by a pawn shop transaction that came to the attention of New Hampshire police.
"Detectives from NH have been down here several days, and it's my understand that they just departed," said Puetz.
Police are now not sure of Dion's whereabouts.
Authorities said Dion is believed to have stolen a silver 2013 Hyundai Elantra, with a Florida license plate number of G673WH. Dion has a history of changing license plates to avoid detection and is possibly living in this car, police said. Dion should be considered armed and dangerous.
Dion has extensive history in the Southeastern U.S., specifically the Atlanta area and Florida.

A $5,000 reward is being offered by the U.S. Marshals Fugitive Task Force for information leading to the arrest of Dion.
"There's every reason to believe at this point that he's left the area," said Puetz. "But we've put out notification to everyone that he is present. We can't eliminate the possibility that he might still be in the area or that he will return."
