SOUTH FORT MYERS, Fla.- Thirteen suspicious, unsolved fires have fire investigators frustrated, and Iona McGregor residents on high alert.

A once quiet neighborhood is now all too familiar with the sound of sirens.
 
"You don't know what's going to happen next. Or where it's going to happen next," Iona McGregor resident Betty Kia said Thursday.
 
The Iona McGregor District Fire Department is calling on its community to help put an end to the rash of suspicious fires, all occuring within a two mile radius.

Crews went door to door Thursday evening to try to establish a community watch.
 
"What we'd like to do is cue them up, if you will, and put them on alert. Say hey, we need your help. We need your eyes, because we can't be there 24/7. You live there, you know who's supposed to be there and who's not supposed to be there," Chief Phillip Brown said Thursday.
 
The fire department is also working with two crime analysts to track the unsolved fires.

Since November, six suspicious fires have started along Thorton Road, with another four on adjacent Live Oak Drive, and three on Kapok Court. The reports began as grass fires, but expanded to cars, storage sheds, and homes.
 
"It seems like it started out as smaller fires, and now each one seems like it's getting bigger and bigger," Iona McGregor resident Larry Doner said.

All 13 of the suspicious fires are currently unsolved, open investigations. If you have any information, you're asked to call Southwest Florida Crime Stoppers 1-800-780-TIPS.
