A series of suspicious fires are under investigation in Miami County.

The Miami County Sheriff’s office says they are looking into six suspicious grass fires in the northern portion of the county. The fires appear to have been intentionally set dating back to an incident on March 12 through another on March 25.

One of the fires caused damage to an exposed gas line along County Road 400 West, north of Macy. The pipeline sustained significant damage of a monetary value but was not deemed a public safety concern.

Five of the fires were started alongside the roadway in the ditch. But a sixth was initiated inside a vacant property near CR 1350 North and CR 400 West.

Local authorities are advising residents in the Macy area to watch for vehicles stopped or slowed along the road and any unusual pedestrian foot traffic. If someone sees something suspicious they are asked to record as much identifying information from a safe distance and notify law enforcement immediately.

The Miami County Sheriff’s Office says it will be saturating the area with extra patrol utilizing both marked and unmarked vehicles.

Anyone with information is asked to contact Detective Sergeant Nathan Freeman at (765) 472-1322, ext. 4444, or e-mail nfreeman@miamicountyin.gov .
