On August 15, 1978, 18-month-old Yohanna Cyr was at an apartment on rue Rochon in Saint-Laurent, Québec.
Her mother, Liliane, was away in the North Shore region for work and had left Yohanna in the care of her boyfriend at the time, Aaron Lewis.
What happened next would become a mystery that has lasted for nearly half a century.
The following day, Lewis contacted Liliane and told her that his parents were looking after Yohanna in Washington, D.C., and that he was coming to visit her. Liliane returned to Montréal with him, but when she learned that her daughter was supposedly in Washington, she traveled there herself to find her.
She couldn’t find Yohanna.
And then, the explanation changed.
A Story That Never Led to Yohanna
Lewis later told Liliane that Yohanna had drowned in a bathtub. He claimed that, frightened and panicking, he had buried the little girl afterward.
But no body was ever recovered.
Lewis was charged with child abduction in a Montréal court. On September 28, 1978, he was acquitted and released after spending several weeks in custody. He was later charged with perjury, but that case also ended in an acquittal.
With no confirmed account of what happened to Yohanna and no remains to provide answers, the case remained open.
Liliane has never accepted the idea that her daughter simply disappeared without explanation. She has said that she believes Yohanna may have been sold.
That remains her belief, however, and there has never been public confirmation establishing what happened to Yohanna.
A Witness Came Forward Again
For years, information surrounding the disappearance remained uncertain.
Then, in 2006, a woman contacted the Missing Children’s Network with a story she said she had originally told police back in 1978. According to her account, she had later withdrawn the statement because she was afraid.
The woman reportedly said she had seen Lewis leaving the apartment on the day Yohanna disappeared, carrying what appeared to be a metal breadbox.
Decades had passed, but investigators continued to examine information that might help determine what happened to the child.
The Search Beneath the Ground
In 2014, investigators returned to the area around Grenet Street, close to where the former apartment had once stood.
Using ground-penetrating radar, authorities searched the location on two separate occasions. Part of the investigation involved excavating an area that had once been wooded but had later become a parking lot.
The hope was that something buried there might finally lead investigators to Yohanna.
Nothing was found.
The search ended without the discovery her family had spent decades hoping for.
Nearly Fifty Years Without an Answer
Yohanna was only 18 months old when she disappeared.
She was too young to explain where she had been or what had happened to her. Everything investigators know comes from the accounts of other people — accounts that have changed, conflicted, or could not be independently confirmed.
And that is what makes her case so painful.
There is no confirmed final sighting that explains where Yohanna went. There are no recovered remains. And there is no definitive answer about what happened to her after she vanished from that apartment in 1978.
But the case has never stopped mattering.
Anyone with information about Yohanna Cyr’s disappearance is urged to contact the Service de police de la Ville de Montréal at 514-393-1133, referencing case 214-02-780905-011.

Nearly five decades have passed, but Yohanna was never forgotten.
She was a little girl when she disappeared.
Her family is still waiting to know what happened to her.
May Yohanna be remembered, and may one day the truth finally bring her family home to an answer.
