Portland authorities say a homeless man has died in a fire at his encampment along railroad tracks in the city. Firefighters responded to reports of a fire on West Commercial Street just before midnight on Saturday. As crews extinguished the fire, the badly burned body of a man was found nearby. The fire also destroyed a tent, some personal belongings and scorched a small area of woods. The victim’s name was not made public pending notification of family. An autopsy is scheduled. Fire Chief Jerome LaMoria says the death highlights the vulnerability of the homeless population who use open flame for heating, lighting and cooking. The chief hopes to establish an outreach program to educate the homeless in fire safety tips.
