does it say his body was ever found? did Neri dump his body in the water?
would have been to sloppy for a body to be dumped in the lake. when fredo and neri left the dock nothing was brought to weigh the body to the bottom of the lake.. and i do not think mike would want to live near a lake where his older brother's body still be and may wash up ... i bet Neri took it ashore.
