(Portland, OR)  --  Fire investigators are looking into the cause of an apartment fire in northeast Portland that left one dead.  Crews were called out just before 3:30 Sunday morning to the blaze on Northeast Glisan near Interstate 205.  The Red Cross was called out to help at least ten-adults and 15-children displaced by the fire.  There's no word yet on what caused the blaze, and it's unclear if the apartment had smoke detectors.
