NEWNAN, Ga. -- The Newnan Fire Department is asking for the public’s help in finding an arsonist that has set at least seven arson fires in a concentrated area of the city since October.

The fires were all near the intersection of of Savannah Street and Pinson Street just southeast of downtown Newnan. The area is just east of the old Howard Warner School building on Savannah Street.

"The fires are being set at a rate of at least one per month," said Gina Snider of the Newnan Fire Department.

The most recent fire was set last week at the corner of Pinson and Savannah. The targeted houses have all been vacant, and the fires are generally occurring at night.

No one has been injured in the fire.. Each of the fires was investigated and determined to be arson. The fires were all set in a similar manner.

“There are a lot of elderly people that live in that area," said Newnan Police Detective Chad Wood.

"It's just a matter of time before somebody gets hurt," said Newnan Fire Marshal Ricky Ayers. "We need help from the community."

Ayers suggested that neighbors in that area be extra vigilant and consider forming a neighborhood watch.

"If you see something that doesn't look right -- especially around vacant homes -- call 911," said Ayers.

There is a possibility of receiving a monetary reward through the Georgia Arson Control Board for information leading to an arrest and conviction.

Anyone with information or who may have noticed something suspicious around the time of one of the arson fires is urged to contact authorities. Wood can be reached at 770-254-2355, Ext. 116.
