(KAIR)--Atchison's Fire Chief say last week’s fire at a historic home at 302 North 2nd Street was accidental.

Fire Chief Patrick Weishaar says investigators found no signs of arson or tampering. That’s after checking nearby security video and interviewing neighbors, with no suspicious activity reported.

The home was vacant but still had utilities and a working modern heating and cooling system at the time of the fire.

According to the State Register of Historic places, the structure, known as the McKelvey House, is considered one of the town's oldest historic homes, recognized as a contributing property in the State Register.

Weishaar, in the release issued exactly one week after the fire, said investigators will continue reviewing evidence as cleanup of the property begins.

Weishaar says the department remains committed to identifying fire causes and offering support to the affected.
