Fire crews and the Allegheny County Fire Marshal's Office were called to a late-night house fire in Carnegie on Saturday, with the incident sending one person to the hospital and filling the 500 block of Flynn Avenue with heavy smoke around 10:15 p.m., according to officials. The cause of the blaze has not been released, and authorities say the investigation is still underway.
Allegheny County 911 logged the call and confirmed that one person was transported to a hospital, with no word yet on any additional injuries, as reported by WPXI. The station also reported that the county fire marshal was called to begin an origin-and-cause investigation at the scene.
What the fire marshal will investigate
According to the Allegheny County Fire Marshal's Office, the county typically steps in to investigate the origin and cause of fires when local departments request help and can deploy the Allegheny County Arson Response Team if needed. Allegheny County notes that such investigations can involve collecting evidence, conducting interviews, and coordinating with county police and the district attorney's office.
Carnegie's recent fire history
Serious blazes are uncommon but not unprecedented in Carnegie, as a four-alarm fire heavily damaged Riley's Pour House in November 2024, with no injuries reported in that case. CBS News Pittsburgh coverage at the time captured the scale of that firefighting response.
Information for neighbors
Anyone who has information or video from the 500 block of Flynn Avenue on Saturday night is asked to contact the Carnegie Borough Police Department or Allegheny County 911. WPXI has described this as a developing story, and more details are expected to be released as the investigation moves forward.
