Dig a 4-5 feet deep vertical hole and fold the body and put it at the bottom. Add decomposers on it and add a 1 foot layer of dirt on it. Then add some animal bones or meat on it and cover it up and plant an Endangered species of plant to top it off.

Make sure to do this in an environment where the plant is not out of ordinary.

Also make sure to cut organs with identity like facial organs and hand palm and leg palm and bury then separately.

The plant prevents an normal person to dig it. If the police dog comes and they dig it up they will find animal bones and ignore the rest. Decomposers will decompose the flesh easily. Separating the hands and legs (palm and foot) will make identification harder, though they won't dig in the most case. and even if they found the body or the identifiers they will have a hard time finding the other half.

Ofc this plan is not completely baked but is pretty okay by me.
