I live in southern Vermont, right on the Connecticut river and Massachusetts border. I'll admit murders and other serious crimes are uncommon in my area, this one old case definitely stands out!
Russell Colvin, then aged 40, went missing from his family's farm in Manchester, Vermont one afternoon in the Spring of 1812. While his body was never located (verifiable anyway), his two brothers in law, Stephen and Jesse Boorn, were later charged with, and convicted of his murder some 7 years later. This case I am quite sure was among the first homicides without a body that resulted in a conviction.
However, there was some doubt among locals as to the two brothers guilt. It was based entirely on circumstantial evidence. The Boorn brothers, and their large family, vigorously protested their innocence and claimed Russell Calvin had absconded, as he's done before over the years during his marriage, and thus abandoned his family. The convicted brothers were due to hang for the offense. Incredibly, within weeks of the execution date, a man claiming to be Russell Calvin arrived by Stage in Manchester village. Townspeople all gathered and there was what seemed to be unanimous agreement this man who's supposedly been dead over 7 years, was indeed a very much alive Colvin. The Boorn brothers were exonerated and their lives spared. This newly rediscovered Russell Colvin left town just as abruptly as he's entered it a couple of days earlier.
Or was it really Russell Colvin at all?
Links: the first link I have here is a short book written about the case, published in 1873, by Leonard Sargent, who was one of the attorneys who worked on the case in 1819. Loaded with information!
Second link is a nicely written article in a true crime blog:
A compendium of information, resources and discussion on notable nineteenth century American murders.
