(Portland, OR)  --  Police are scheduled to release more details today, after a man was killed in a shootout with officers and his two young daughters were found dead.  Both Portland and Gresham police officers responded to a report of a domestic-violence incident early this morning, with a woman telling the 911 operator that her husband was armed and had threatened the girls.  Gresham officers spotted the man's SUV in a plasma center parking lot in the 16-thousand-200 block of Northeast Glisan Street, then encountered gunfire.  The man was shot dead, then the officers pulled the bodies of the man's daughters, ages eight and eleven, out of the SUV.  Police say it's not clear how the girls died.
