(Portland, OR)  --  A man is facing multiple charges after allegedly banging on a homeowner's door while holding a gun.  Police arrested 25-year-old Daniel Schniedewind at a home on Southeast 141st Avenue early yesterday morning.  Police say the homeowner called 9-1-1 instead of answering the door.  Arriving officers found a concealed, loaded firearm on Schniedewind and arrested him on charges of first-degree trespassing, possession of a loaded firearm and felon in possession of a firearm.  Investigators say they don't know Schniedewind was banging on the man's door.
