Just after 11:30pm, HFD responded to a reported apartment fire in the 3500 block of Sampson. Firefighters arrived to find a fire on the side of the building on the first floor, with flames extending to the unit above. Firefighters were able to quickly douse the flames and prevent extension into the attic. The downstairs area appears to possibly be a business or used to be as the building appears vacant. Arson investigators are on scene for the investigation.
