PEORIA, Ill. -- Investigators say two fires at the same apartment building this week are not arson.

Firefighters were called to 109 Roanoke Avenue in Peoria twice this week.

The first fire was Monday in an attic. Investigators believed that fire was caused by electrical issues.

Another fire on Tuesday engulfed the third floor of the building.

Investigators believe it was caused by smoldering insulation not detected in their initial investigation.

"If we had a fire that would have been a rekindle, we would have seen a lot more damage where the first fire occurred, but we don't. That is why we believe we had this other smoldering event on the other side of the fire wall,” said Peoria Fire Department Fire Investigator Brad Pierson.

Investigators said the manager of the property has had code violations in the past. They did not say if either fire was the result of any violations.

Investigators said another fire in that building last year remains under investigation.

Overall damage is estimated to be $500,000. The building will be demolished.
