SOUTH FORT MYERS, Fla -  Iona-McGregor firefighters are investigating an overnight duplex fire they say is suspicious.

This is one of nearly a dozen suspicious fires in the Iona-McGregor community in just the past few months.

The latest fire is on Kapok Court and other streets near McGregor Blvd. fear there is an arsonist on the loose.

"It was just an orange glow. It was so scary," said Alice Fasig, a neighbor.

A fireball lit up the sky over South Fort Myers.

This vacant duplex erupted in flames shortly after midnight.

The flames were so high they nearly spread to neighbor Alice Fasig's home.

"It could have been devastating. We could have been dead," she said.

Multiple crews from the Iona-McGregor Fire Department responded to the scene and battled the blaze for several hours.

"This particular fire is suspicious in nature at this time," said Phil Brown, from the Iona-McGregor Fire Department.

Fasig agrees.

She says someone has been setting fires in this area for months.

"What's going on? Is somebody getting their kicks this way? It's not right. I hope they catch them," she said.

Since October several suspicious fires have been set inside sheds, grassy areas and boats.

All have been near McGregor Boulevard and the Thornton Road area.

"I fear coming home and finding my house gone," said Bob, another neighbor.

Bob, who didn't want to use his last name, lives on Thornton Road.

In October his boat went up flames.

A few weeks later, several areas of grass around his home were also intentionally set on fire.

"This is not a coincidence. Anyone who says this is a coincidence is just pulling your leg," Bob said.

Neighbors worry the suspects are getting more brazen

Monday morning's is the first time a home went up in flames.

"They are getting bigger. These fires are just dangerous," Bob said.

Alice Fasig counts her blessings happy the fire didn't spread.

"We could have been dead. that could have been the worse thing. but losing all our possessions, everything to some prank. Somebody getting their kicks. That's wrong," she said.

The Lee County Sheriff's Office has beefed up patrol in this area.

 Neighbors are also keeping a watchful eye.
