The source of a suspicious fire which destroyed a trailer on Ivy Street over the weekend remains under investigation.

Firefighters reported to the fire at 8:24 p.m. Saturday to find the north end of a trailer ablaze.

Investigators later ruled the source of the fire as suspicious.

This is the eighth fire inside the city in just over two weeks and the third with a suspicious origin.

City Fire Investigator Steve Copeland said Saturday's fire started in a bedroom of the unoccupied trailer.

"There was heavy damage to that side and smoke damage throughout," he said. "It was a total loss."

Copeland noted that all utilities were turned off and no accelerants were found.

Since Nov. 28 there have been eight fires inside the city: one that damaged a downtown salon and law office; one that destroyed a Philadelphia High School concession stand; one at McKee's Pawn Shop; a truck fire next to the Neshoba County Courthouse; a house fire at 1004 North Donald Ave.; a house fire at 265 Railroad Ave.; a kitchen fire at 1108 Myrtle St. and the fire on Ivy Street.

The concession stand and pawn shop were labeled arson. No arrests have been made but a juvenile is wanted for questioning in connection with the school fire.

Evidence from the concession stand at the high school pointed to arson, after a candy sucker was discovered a few feet from the scene, Copeland said.

Authorities believe theft was the possible motive.

At McKee's on east Main Street, a pair of weed eaters and a security screen were damaged by the fire, Copeland said. The building itself sustained no damage.

Meanwhile, authorities have determined that a heater on a wall in an empty office used for storage was the cause of a Thanksgiving Day fire which damaged Shear Gossip beauty salon and Mars, Mars and Mars on Center Avenue.

"The heater was in the storage room and burned through the wall into the salon. The whole wall burned out," Copeland said.

The fire was reported at 6:48 a.m. and spread from the storage room into the salon but was extinguished before it spread to the rest of the building, the fire report said.

The beauty shop received fire, smoke and water damage while the law office received smoke damage. A shared attic between the two received both fire and smoke damage.

Copeland noted that this time of year always sees an increase in fires, mostly from people trying to heat their homes.

In January 2012, three children died and two adults and another child were injured in an early morning fire in the Fairview community. The fire started when a towel fell onto the kitchen stove while it was being used to heat the home.

"People try unconventional ways to heat their homes," he said.

With the number of recent fires, three of them suspicious, Copeland also urged all citizens call the police if they see any suspicious activity.
