Lacassagne had based his estimate on the corpse’s teeth. Dental forensics were in as primitive a state as dentistry, and Lacassagne’s achievement here was another breakthrough: he judged the wear of the dentin in the teeth, the amount of tartar at the roots, and the thinness of the roots themselves to produce his estimate.
Lacassagne clinched the identification with a hair from one of Gouffé’s hairbrushes. He compared it under the microscope with a hair from the corpse, checking for hair-dye residue, which came up negative. Then he measured the thickness of the hairs and found them identical. Certain in his conclusion, Lacassagne dramatically addressed Inspector Goron: “I present you with Monsieur Gouffé!” 38
“The Corpse Has Been Identified,” trumpeted the Paris newspaper L’Intransigeant on its front page the following day, November 22. The newspaper ran two illustrations side by side — one showing the decomposed head of the corpse and the other the face of Gouffé in life. “It Is He,” the headline crowed. Other newspapers treated their readers to the gory details and stressed the glory of French forensic medicine. Le Petit Journal paid tribute to Dr. Lacassagne’s skills, concluding, “The solving of the mystery of Millery demonstrates that French medicine can show criminology the way to great progress in the future. Identification of the Millery corpse is a milestone in history.” 39
Goron was content for now to let the spotlight shine on someone else and to take up the next stage in the case: finding who killed Gouffé. The brother-in-law was now shown police photos of several known criminals. Goron was pleased when he identified pictures of Michel Eyraud and Gabrielle Bompard as the pair previously seen with Gouffé. On his return to Paris, Goron had found yet another witness who linked the lovers to the murdered man. But Eyraud and Bompard seemed to have dropped out of sight.
Goron was creative in his search. He hired a carpenter to make an exact copy of the rotten trunk that had been used to take the body to Lyons. Put on display at the Paris morgue, the trunk attracted some thirty-five thousand curious viewers in the first three days. Photographs of it were sent around the world. The Gouffé family offered a reward for information, and letters poured in from all over France. Soon Goron heard from a man in London who claimed that a Frenchman and his daughter, later identified as Eyraud and Bompard, had lived in his lodgings and before departing had bought a trunk like the one shown in the newspapers.
A police spy in Paris gave Goron more important details. Michel Eyraud was an army deserter and a small-time crook and, though married, had taken up with a prostitute, Gabrielle Bompard. The two of them operated the traditional badger scheme: Bompard would take a client to her apartment, and after a suitable amount of time, Eyraud would burst in, pretending to be her husband. He would threaten the john, who was usually ready to pay to get out of the situation.
The con worked well, but Eyraud was a greedy man. One of Bompard’s clients was Toussaint-Augustin Gouffé, who had foolishly let her know that he kept large sums of money in his office. Eyraud, Goron’s spy reported, had decided to kill Gouffé and take the money.
Despite massive newspaper coverage and the fact that photos of the pair were sent to police throughout Europe and North America, they managed to keep one step ahead of the law. They reached San Francisco, where Bompard met another man who fell for her charms. She ran off with the American after telling him that Eyraud planned to kill her. Jealous, Eyraud pursued the pair, tracking them from city to city.
It was not until January 1890 that Goron firmly connected with the culprits — not through detective skills, but by sheer luck. A resentful Eyraud sent him a letter, protesting his innocence and putting all the blame on “that serpent Gabrielle,” whom he accused of
