Unified Fire Authority crews rushed to the scene of a Millcreek house fire twice within a 12-hour period. Now, the possibility of arson is being investigated.

The woman living in the home at 2247 E. Atkin Avenue (2830 South) had left to stay with family after the first fire, reported about 4:30 p.m. Wednesday, had billowed smoke from the eaves and killed her four pet dogs.

Then at 4:37 a.m. Thursday, flames were reported engulfing the home. UFA Assistant Chief Marty Slack called the second fire "suspicious," and said arson investigators were called in.

He noted that no evidence was initially found that either fire was intentionally set. Authorities were not ruling out that the second fire may have erupted from some previously unseen hot spot or smoldering embers.

To make sure the fire does not reignite again, crews planned to be at the scene throughout Thursday. The home has been determined a complete loss and was being demolished.
