Haha. You know what they say, good friends will help you move, but great friends will help you move a body.
I actually only learned about aqua-cremation recently after seeing it in an obituary and doing some research on it. It's very eco-friendly - requires much less energy, doesn't release pollutants into the atmosphere, environmentally safe to dispose of into even residential sewer drains, and, well, it's full of nutrients. Apparently some funeral homes have deals with farmers, who come and spread the stuff on fields, although I hear the smell is pretty godawful. "Like a million clams baking under the sun" is how I heard it described.
Also Dexter is pretty great, but totally not how I'd be a serial killer. His compulsions make it way harder than it has to be. Last year in Chicago, for example, cops only solved 15% of homicides. Doesn't take a genius to figure out that it doesn't take a genius to get away with murder.
They also recently found evidence that a serial killer with possibly 50+ victims has been operating in the Chicago area, and they didn't even know about the possibility that said killer existed until AI-assisted statistical analysis showed it was virtually guaranteed.
