CANTON, Ohio (WJW) – An apartment fire that killed one person and injured a firefighter in Canton has been ruled arson.

The State Fire Marshal determined the flames that erupted at the large two-and-a-half-story home than had been converted into a five-unit apartment were intentionally set.

The fire on Raff Road SW broke out at about 11:30 p.m. on Thursday, September 29.

When crews arrived, they found fire and thick smoke. Officials said, three people were rescued from the building. A 71-year-old man was unconscious and taken to the hospital where he later died, according to officials.

A firefighter was also hurt and taken to the hospital, with non-life-threatening injuries.

Officials are now asking for the public’s help to identify who is responsible. The Canton fire chief said in a press release, “This is now an active murder investigation.”

The Blue Ribbon Arson Committee is offering a reward of up to $5,000 for information leading to an arrest and conviction.

Anyone who has information should contact the State Fire Marshal’s tip line at 800-589-2728 or The Canton Fire & Police department dispatch tip line at 330-649-5900.
