Oh yeah, one more. Regarding catfish and dead bodies.
I'm a scuba diver, but never went for police scuba work, because I prefer my water clear and blue. Grabbing a wet decomposing corpse in cold, dark, opaque water is not my idea of fun. I convinced a buddy to do it, however, telling him he'd get great training. He got the training, and a whole lot more.
A couple years ago, they drained Lake Shafer, up north of where I live, so that folks could repair piers, etc. When they did so, they discovered a car that'd gone off the road MANY years ago. This was the missing car that contained two college boys who'd been missing. Speculation had always been a murder, or kidnap/murder, because the last place they'd been seen was as strip club in a rough part of a neighboring town.
Anyway, the lake goes down, they see the top of this car, and call the State Police dive team to come help get it out, and process it as a crime scene. My buddy goes up there, helps rig the tow lines to yank the car, and they drag it up to dry land. It's full of water, of course, so they open the doors to pour out the water, and along with the water comes this GIGANTIC catfish! All the windows were rolled up to just a crack, so we reasoned that a tiny catfish had swam in through the vents, started eating the boys (oh, yeah, both boys were there; turns out they'd just missed a turn and driven into the lake, not been murdered), and grown too big to swim out! So for God only knows how long, this gigantic, corpse-engorged catfish had been lurking there in this submerged car, too big to escape! They kept the catfish for several hours in the bottom of one of the dive boats, but nobody wanted to keep a fish that'd eaten the boys, so they eventually released it, after taking dozens of pictures. I was amazed that something that big could live on the oxygen in the water that ran through the vents, but then, catfish are tough. I can't imagine how big the fish must have been before it started atrophying from lack of food.
So you could say there's actually a "man-eating" catfish in Lake Shafer.
