Does a 200-Year-Old Gourd Contain the Blood of a Beheaded King?

Dried blood on a handkerchief, a $700,000 gourd and one dead king. A forensic murder mystery? Nope, just another genetics paper. I mean, it is gourd season, what did you expect? The dead king in question is Louis XVI (the last of the French kings), who was ceremoniously beheaded on January 21st, 1793. After the beheading, attendees rushed the stage and dipped their handkerchiefs in the royal blood. Over two hundred years later, some of that blood may have been found--dried to the inside of a decorative gunpowder gourd. The story goes that one of the attendees rushed home and stuffed the bloody handkerchief into the gourd for safekeeping. In a study published in the journal Forensic Science International: Genetics, researchers analyzed some of the dried blood scraped from the inside of the gourd to find out if it really could be the king's blood. They checked the Y chromosome to see if the blood-donor was male, and checked for the presence of a blue-eye gene, HERC2. The blood was indeed from the correct time period and belonged to a blue-eyed male--so far, the evidence fits the blue-eyed king. More genetic information about the family will be needed to confirm the identity, the study's lead author told Wired's Dave Mosher:
