KOKOMO, Ind. (AP) – Authorities are hoping a new reward offer will help find out who set a central Indiana house fire that killed a woman and three children more than a decade ago.

Kokomo police investigators recently began again reviewing evidence and witness statements from the February 2005 fire that engulfed the family's home in flames and smoke. Authorities determined the fire was deliberately set.

Detective Scott Purtee tells the Kokomo Tribune (http://bit.ly/1bODxQu ) that someone knows what happens. The $5,000 reward is being offered through the Indiana Chapter of the International Association of Arson Investigators.

Smoke inhalation from the blaze killed 25-year-old Amy Parrish; her sons 4-year-old Dacota Rasmussen and 2-year-old Caleb Parrish; and 11-year-old stepson Casey Parrish. Parrish's husband and father of the children escaped the fire and survived.
