Two people suffered minor injuries in a blaze that destroyed a firefighter’s home in Greenfield Friday morning. A mother and her two teenage children jumped 15 feet out the window to escape the fire with the help of Greenfield police officer Josh Mullins. The mother and Mullins suffered minor injuries. The family’s father is a firefighter and was on duty at the time of the 2 a.m. fire. Arson investigators do not believe the fire was intentionally set.
