State fire investigators are trying to identify a person seen walking on the road Tuesday near a vacant, condemned house at 9 Oxford St. in Mexico that was heavily damaged by fire.
The individual, investigators say, may have information about the fire, which was reported just before 7:30 p.m.

The Office of State Fire Marshal has classified the fire as incendiary, according to a release from Shannon Moss, spokeswoman for the Maine Department of Public Safety.
The National Fire Protection Association defines an incendiary fire as a fire intentionally ignited in an area or under circumstances where and when there should not be a fire, according to online sources.
Mexico fire Lt. Jamee Theriault said Wednesday there was no electricity or other utilities at the boarded-up house that the town was set to tear down.

About 20 firefighters from Mexico and Rumford departments responded to the blaze Tuesday night. No injuries were reported.
Investigators are asking nearby residents and businesses to check their security or surveillance cameras for any activity that could be relevant.
Anyone with information is encouraged to contact the Office of State Fire Marshal at 207-624-7076. The investigation remains ongoing. Additional information will be released as it becomes available.
