WAVE TV (http://bit.ly/ITv6o2) reports there have been more than a dozen reports this year of blazing wreaths in neighborhoods around the city.
Investigators say they think the same person is responsible for all of them.
Metro Arson Major Henry Ott says his department began investigating similar cases since last December. He says they are looking at a total of about 35 fires.
All the blazes happened in the overnight hours, and Ott says most of them resulted in minimal damage.
