The Mystery of the Puget Sound Salmon Killer

Six P.P.D. ...Coueno? Boy, you got titers in your ears. Huh? And this is a chemical that's found in tires? I don't know. Then the rain comes along and sweeps it right into the creeks and rivers where the fish live. Bingo. Looks like they've been doing some rather intense detective work of their own. In all the years since, I've never forgotten about that case. Some say it was luck. Others say it was only a matter of time until the killer was cut. I say it was destiny.
