Eliane St. Pierre disappeared forever during a date with Henri-Emile Fissiault but he couldn't remember anything

 Miss Elianne St. Pierre, 21, went on a date with Henri-Emile Fissiault, 29, on 3 November 1936 and that was the last anybody saw of her or her body. 

 Her disappearanced ignited an unprecedented firestorm of rumour, gossip and speculation in Montreal.

 It was clear that Fissiault killed her and he didn't deny it. He just said he couldn't remember anything.

 Police found blood and hair in his car but he never faced charges.  

 Although never punished, Fissiault could not not avoid his gruesome fate.

 St. Pierre had left convent at the age of 17 and worked in a pharmacy and lived at 7744 de Gaspe St. She was supposedly engaged to a French Canadian living in Chicago. 

 Her uncle Armand Brodeur headed Montreal police's Detective Bureau. Her father ran for the post of city councillor in St. Henri.

 Fissiault was either a traveling salesman or the president's assistant and lived with his brother and sister-in-law at 2214 Tupper.

  One of countless articles on the couple reported that he was engaged to another woman but was also wooing St. Pierre in hope she'd marry him. His uncle was a judge.

  Fissiault picked St. Pierre up at her work in his green 1932 Chevrolet on 3 November and drove her to his office at The Bulldog Grip Cement Company of 2101 Bennett St. 

 According to one witness, the two argued. Police found blood on the premises. She was never seen leaving the building. 

 Fissiault told police that he drove off with St. Pierre but couldn't remember anything of it. He said he woke up the next day in St. Eustache. 

 Police searched his car and found human hairs, a hatchet and 100 .22 calibre shells.  

 On 9 December Fissiault was to be charged with kidnapping but a judge dismissed it due to lack of evidence. 

  The Crown then filed a murder charge and desperately sought St. Pierre's body in a river in St. Eustache, going to great lengths to scrape the river bed and send divers in to search. They even tossed dynamite into the waters in hopes that it woudl make a body float to the surface. 

 The search came up empty and was reluctantly called off.

 Police also searched an area around Decarie Boulevard, where Fissiault had also visited on the fateful day but they found nothing. 

 Without a body prosecutors had no case and on 22 December the Crown Prosecutor withdrew the murder charge.

 Fissiault and his brother changed their names and moved to another part of town. 

 Police pressed on searching for St. Pierre's body but never found it.

 Eight months after St. Pierre's disappearance - specifically at 3 pm on 16 July 1937 - police were called to the home of Fissiault's employer Hector Beaupre at 156 Bloomfield, Outremont, where Fissiault had been staying. 

 They found Fissiault's body hanging from a clothesline in the basement. 

 He was dead and his mouth had been stuffed with human hair.

 Newspapers reported on the suicide in great detail and some articles described the autopsy results as mysterious. 

 The affair inspired newspapers to report and evaluate every sort of gossip, with one common theme claiming that St. Pierre was still alive. 

 One article stated that Fissiault was actually a homosexual. Another said that his suicide was actually a murder.  

  One reported that St. Pierre was not dead but rather was the same person as Lilian Morel, who had killed a guy a couple of years earlier.

 In 1945 a life insurance was finally convinced that she was dead and paid her survivors  $1,000.
