North America, Washington state: just outside the city limits of Camas

Officer Mac Murray stared down at the corpse of Emilee Knighthound. She had been slashed to ribbons by a fish knife, which lay nearby. Her naked body almost shone pallid blue from chill. Her clothes were folded neatly further up the shore.
Her glassy black eyes stared out over the opaque, unforgiving currents of the Columbia, long strands of her hair mixing with the bloody, slapping shallow waves.
" This is disgusting."
Mac turned to face the coroner, Doctor Whitney ' Whit' Turnjudge was a small, slim man, with a tendency towards bookishness. His cheeks were pink from the bitter morning chill.
" I've never seen a murder with this kind of raw anger behind it. See the rope?""
Mac squatted down and looked at the rope tying Emmilee's feet together, then a length of heavy chain leading up the shore to wrap around a sturdy tree.
" Yeah..?"
Whit adjusted his glasses.
" I think this is something that poachers sometimes do to large female sturgeon. They'll catch the fish, tie them to something, keep them tied up until they find a buyer, then open them up and make off with the eggs."
Mac gagged but kept his head.
Whit continued to speak.
" This does remind me of something I saw on the news the other day though."
Mac perked up.
" What was it?"
" A kingpin player in some Beluga sturgeon poaching ring was found tied up in his garage, naked, upside down, and gutted just like a fish." Whit said, grimacing.
" Maybe there's some sort of poacher punishing syndicate operating worldwide." Mac joked.
Whit considered it.
" Maybe. I'll do some research tonight on poacher deaths."
Mac nodded.
Among the gathering crowd, the Night lady slid away, content that North America's largest freshwater fish didn't need to fear this poacher any more.
