7. Emile Gourbin
Edmond Locard was a pioneering criminologist known as the “Sherlock Holmes of France.” At present, he’s finest remembered for Locard’s trade precept, a necessary postulate of forensics which is finest summed up as “each contact leaves a hint.” He proved this idea on a number of events, such because the homicide of Marie Latelle in 1912.
Marie was discovered strangled in her dad and mom’ residence in Lyon. Police suspected her boyfriend, Emile Gourbin, however he produced a bunch of witnesses who testified that he had performed playing cards with them that night till late at evening.
