First one brush fire, then another 100 yards away, still another a mile away and yet another 2.5 more miles down the road.
All four burned Friday afternoon within a four-mile area in central Bienville Parish.
That led Bienville Parish Fire District 6 firefighters to call deputies about 2:45 p.m. that day.
Now the the fires in the area of the villages of Bienville and Bryceland are being investigated by the Louisiana fire marshal's office.
Authorities say it appears most of the fires were started from the roadway.
A fire on Shiloh Road burned 100 yards north and 10 feet into the woods, the fire marshal's office reports.
A hundred yards away on the same road, another fire burned 200 yards north and 50 yards into the woods.
Many trees in the area of the that blaze show evidence of charring up to six feet high, according to the fire marshal's office.
Louisiana Agriculture & Forestry Department workers had to cut fire lines to stop the fire's spread.
Then there was a fire a mile away that burned part of a pine plantation in the 1000 block of Shiloh Cemetery Road.
Investigators think it was started near the roadway and across from a hunting camp.
It spread to the north and south to the tune of 500 yards across and 200 yards deep.
A passerby reported the third fire then called it in again when the flames neared a well site.
The same person reported having seen a white, newer model, single-cab Chevrolet pickup with a long wheelbase backed up on a well site road.
The truck had no markings on it, the witness told authorities.
The fourth fire was reported when someone saw smoke along Louisiana Highway 517 about 2.5 miles from the Shiloh Cemetery Road fire.
That fire burned a 100-foot circle in the middle of a small grass field between a house and an old wooden barn, authorities said.
"Investigators have deemed these fires connected and incendiary ...," the fire marshal's office reports.
Authorities urge anyone with any information to call the state fire marshal's toll-free arson hotline at (866) 946-1097.
