The body of the resident who died after barricading himself into a house at 1100 Mt. Hood Street in The Dalles on Monday has been sent to the Oregon Medical Examiner’s office in Clackamas to determine the cause of death and make a positive identification.  Wasco County Sheriff’s Chief Deputy Lane Magill says investigators are working on piecing together what happened inside the house after deputies heard gunshots when they attempted to serve eviction documents Monday morning.  Soon after that smoke began coming out of the eaves of the house, and a little more than four hours later the house began to be consumed by fire that produced thick black smoke.  Mid-Columbia Fire and Rescue crews discovered the body after the blaze was extinguished.  Officers set up a perimeter around the house and attempted to negotiate with the occupant, but never received a response at any time during the incident.  Magill says they are trying to piece together how the person died and the cause of the fire.  He adds it may take until Wednesday to reach next of kin and announce the identity of the resident.
