Authorities are trying to determine if a fire that caused $1 million damage to an Oriental rug business in McKees Rocks was intentionally set and whether it had anything to do with graffiti sprayed on the building over the weekend.
The Allegheny County fire marshal and federal officials are investigating the fire at Linder's as a possible hate crime because the words "Iran" and "terrorist" were found sprayed on the building days before Wednesday morning's fire.
The former church that burned is owned by an Iranian man who stores and shows antique and hand-woven rugs there.
Officials were still searching for the cause of the fire Friday.
They say it started inside the business even though all the doors and windows appeared to be secure.
Firefighters had to chop through heavy church doors to get in.
