Strangulation: The Murder Of Daniel Hugon

Daniel Hugon was convicted of a strangulation-murder of a Paris prostitute on October 13, 1968. He was convicted by the French court in Pigalle district of Paris. He was only sentenced to 7 years due because he had evidence of having an extra Y (XYY) male chromosome. There was evidence in previous murder cases, the convict had also had the extra Y (XYY) chromosome. Richard Speck, a Chicago convict with an extra Y (XYY) chromosome, was held responsible for murdering eight nurses in 1966. Sean Farley, a New York convict who also had an extra Y (XYY) chromosome, brutally raped and murdered a woman in 1968. Excluding the extra Y (XYY) chromosome, there were other common features between these convicts. They all had been tall males with a low mentality,

and had an aggressive approach to their murders. Sean Farley was first case to be brought to trial to defend that the act is not guilty unless the mind is guilty. There was a defense that if an individual had a past of difficulties controlling their psychiatric wellbeing, that they are mentally incapable of plotting an intention murder. Their defense on genetic theory of insanity wasn’t strong enough to prove Farley not guilty, and he was convicted.
Recently, there has been an increase of males in prisons, maximum security, and mental hospitals who obtain the same structure as males who obtain the extra Y (XYY) chromosome. It is questionable to claim that this genetic deformity is more commonly present in prisons, than in the general population, since there are no conclusive results. However, the males in hospitals for the criminally insane have shown higher incidences of the deformity than in the general population, but many of these individuals are in there as a life sentence.
