Not all the stories are myths. When Admiral Nelson was killed at Trafalgar, his body was placed in a cask of either rum or brandy (I forget which) and shipped home to England. The sailors who removed the body from the cask and placed it in a coffin are said to have drunk the rum/brandy.
One of Queen Victoria’s sons-in-law, Prince Henry of Battenberg, died of disease in Africa while on a military campaign and was likewise shipped back to England in a barrel of booze.
My dad or my husband…I forget which…recounted a story about someone who was cut into pieces, stuck in a barrel, and floated down the Chicago River a looong time ago.
Warning though, the founder of that forum believes that Patsy Ramsey killed Jonbonet. Do not bother arguing the point. It is still a decent source of information for various missing persons cases, and they also have news and updates on various crimes. (With a lot of editorial comment that would get a person “Modslapped” here.)
