Call me stupid, but I had no idea that non-cremated human remains can be buried at sea. From the EPA: "Burial at sea of human remains that are not cremated shall take place at least 3 nautical miles from land and in water at least 600 feet deep. All necessary measures shall be taken to ensure that the remains sink to the bottom rapidly and permanently." (However, there's no information provided as to what the necessary measures must be to make sure the body sinks rapidly and permanently.)
Apparently, the Lasky family of North Carolina attempted to carry out the dying wishes of Daniel Lasky by burying him at sea, but his body surfaced a day later and all hell broke loose off the coast of Fort Lauderdale, FL (Mr. Lasky specifically requested the area because he loved to vacation there). Homicide began investigating, suspecting foul play, but then found the man's obituary online.
Pretty crazy. And awesome.
