Updated:ORLANDO, Fla. —
The State Fire Marshal’s Office is investigating several fires near downtown Orlando that investigators said are suspicious.
Orlando firefighters were called to four fire scenes late Saturday night and Sunday morning in the Thornton Park area.
Flames tore through vacant homes on Park Lake Street and Christor Place Saturday night.
On Sunday morning, crews were called to a fire at another vacant home on Hill Avenue, right behind Howard Middle School, which was also damaged.
Investigators think all of the fires could be the work of an arsonist.
"(In) some of the incidents we had multiple ignition sources, so it appears the crawl space is where someone is starting the fires,” said Orlando Assistant Fire Chief Keith Maddox.
Fire officials are asking residents in the Thornton Park area to be vigilant.
“Obviously, a dark neighborhood like this at night, anybody walking about abandoned buildings, you need to keep an eye on them,” Maddox said.
Investigators are also working to determine if the fires are related to a series of fires in the same area that were reported in June.
At least three vacant homes were damaged in the June fires.
No arrests have been made in connection to that investigation.
