The  Multnomah Channel seems to be a dumping ground. Several years ago I was there fishing, we were trolling for salmon and all of a sudden my pole and line started goin crazy, thought I had a fish on, jumped up, grabbed my pole only to see that the line was wrapped around  a BODY.  The body was floating.   Had not been  in the water very long, looked fresh.   It appeared to be a neatly dressed, groomed late 20's aged white male,  Nice Suit etc.,   The problem, a large BULLET hole in his temple.  Called 911.   They asked us to stay by the body.   So,  Backed up, got my line back.   It took Harbor Patrol approx. 20 minutes to get there.  They flopped the body up on their boat deck.  They told us, We know  this guy.  He was a extremely well known  local "Business Man", involved in Pimping, Drugs, Gambling, Mafia connections etc.  

We did not catch any salmon that morning, I think the body scared the fish away!!!!!!!!!!!!!!!!!!!!!!!!!
