In November 1990 two Metro Toronto detectives sat down with a twenty-six-year-old trainee accountant named Paul Bernardo and asked him about a string of rapes in Scarborough. People who knew him had called in after a composite sketch was published that spring, saying the drawing looked like him. He was polite, he cooperated, and he gave samples of blood, hair and saliva. Then the samples went into the queue at Ontario's Centre of Forensic Sciences, where they sat, untested, for roughly twenty-six months. The results did not reach police until early 1993. By then Tammy Homolka, Leslie Mahaffy and Kristen French were dead.
That gap is the center of the Bernardo case. It explains why he became a household name in Canada, why two separate provincial reviews picked the investigation apart, and why the country's police forces changed the way they handle serial crime. The murders were committed by a man police had already interviewed, whose DNA they already held, and who lived about an hour's drive from the detectives who were looking for him.
The Scarborough attacks began around one in the morning on May 4, 1987, when a young woman was raped minutes after stepping off a bus near her home. The pattern held for three years. The attacker waited near bus stops in the eastern Toronto suburb, followed women and teenage girls as they walked home at night, and seized them from behind. The Canadian Encyclopedia counts up to twenty-four rapes and attempted rapes in the series. The press called him the Scarborough Rapist. Metro Toronto police formed a task force, and after an attack in May 1990 they released the composite that brought in the calls naming Bernardo.
He did not look like the man the public imagined. Born August 27, 1964, he had grown up in Scarborough, earned a commerce degree, and worked at Price Waterhouse. He was handsome, well dressed and sociable. In 1987 he met Karla Homolka, a seventeen-year-old from St. Catharines who worked at a veterinary clinic, and by 1990 they were engaged. After he lost the accounting job he made money smuggling cigarettes across the border from the United States.
Tammy Homolka was fifteen, Karla's youngest sister, a high school student who adored her future brother-in-law. On the night of December 23, 1990, after a family Christmas gathering at the Homolka house in St. Catharines, she was given drinks laced with sedatives, and Karla held a cloth soaked in halothane, an anesthetic taken from the clinic, over her face. Bernardo raped her while Karla helped and the camera ran. Tammy vomited and stopped breathing. The couple dressed her, cleaned the room and called for help. She died early on Christmas Eve, and a coroner treated the death as an accident. Nobody connected it to the man Toronto detectives had interviewed a month earlier.
By the summer of 1991 the couple were living in a rented pink house on Bayview Drive in Port Dalhousie, the lakefront corner of St. Catharines. Homolka later testified that in June and again in August that year they drugged and assaulted a teenage girl she knew, who survived and has been identified in court only as Jane Doe.
Leslie Mahaffy was fourteen, a Grade 9 student at M.M. Robinson High School in Burlington, a few weeks short of her fifteenth birthday. On the evening of June 14, 1991, she went to the wake of a friend, Chris Evans, who had been killed in a car crash that week with three other teenagers. Afterward she stayed out late with friends in the woods, grieving. She got home near two in the morning and found every door locked. She called a friend from a pay phone to ask if she could sleep over, was told no, and walked back to wake her mother. Bernardo was in the neighborhood, he later said, stealing license plates. He talked her toward his car, blindfolded her, and drove her to Port Dalhousie.
She was held for about a day. The couple raped her and recorded it. Bernardo strangled her, and afterward he cut her body apart with a circular saw and set the pieces in blocks of concrete, which he sank in Lake Gibson south of St. Catharines. When Leslie did not turn up at the funerals for Chris Evans and the others, her mother called police; on June 18 the paperwork listed her as a runaway. On June 29, 1991, a couple canoeing on Lake Gibson found one of the blocks. That same afternoon Bernardo and Homolka were married in a lavish ceremony at Niagara-on-the-Lake.
Kristen French was fifteen, in Grade 10 at Holy Cross Secondary School in St. Catharines, a competitive figure skater who walked home from school the same way every day. On the afternoon of April 16, 1992, the Thursday before Easter, a car pulled into the parking lot of Grace Lutheran Church on her route. Homolka got out holding a map and asked for directions. When Kristen leaned in to look, Bernardo came up behind her with a knife and forced her into the back seat. A witness saw part of the struggle and a shoe was left in the lot. She was held in the Port Dalhousie house for three days, raped repeatedly and filmed, and killed on or about April 19, Easter Sunday. Her body was found on April 30 in a roadside ditch in Burlington.
Her classmates chose a green ribbon as the symbol of their search while she was missing, and the Green Ribbon of Hope became a national campaign for missing children that outlived the case.
The Niagara investigation that followed was enormous and mostly pointed the wrong way. A witness's description sent police looking for an older cream-colored Camaro, and a task force at Beamsville worked through thousands of tips. Metro Toronto and Niagara police did not share what they knew. Toronto had a Scarborough suspect with a St. Catharines address and a sample on file; Niagara had two murdered girls and did not know he existed.
The collapse came from inside the marriage. On January 5, 1993, Bernardo beat Karla with a flashlight so badly that her family took her to hospital, and she pressed assault charges and left him. Around the same time the lab finally ran his samples and matched him to three of the Scarborough attacks. Toronto detectives interviewed Karla, and within days she was telling a lawyer what had happened in Port Dalhousie. Bernardo was arrested on February 17, 1993.
What happened next is the second scandal in the case. Police searched the Bayview Drive house for seventy-one days and missed the videotapes, which Bernardo had hidden above a pot light in a bathroom ceiling. On May 14, 1993, prosecutors agreed to let Homolka plead guilty to two counts of manslaughter in exchange for her testimony, and on July 6 she was sentenced to twelve years. She presented herself as a battered and coerced wife. The tapes would have shown otherwise, but on May 6, following written instructions from his client, Bernardo's lawyer Ken Murray had gone into the house and taken them out of the ceiling. He kept them for about seventeen months and turned them over only in September 1994, after the Homolka deal could no longer be undone.
Murray was later charged with obstruction of justice. On June 13, 2000, Justice Patrick Gravely of the Ontario Superior Court acquitted him, finding a reasonable doubt that he had meant to obstruct justice, since he may have believed he could hold the tapes for use against Homolka at trial. The Law Society of Upper Canada withdrew its misconduct charge that November.
Jury selection for Bernardo's trial began in Toronto on May 1, 1995, before Justice Patrick LeSage. Homolka spent seventeen days on the witness stand. Bernardo's defense, led by John Rosen, admitted that he had kidnapped, confined and sexually assaulted both girls, and argued that Karla had killed them and that he was guilty at most of manslaughter. The jury did not accept it. On September 1, 1995, he was convicted on all nine counts: two each of first-degree murder, kidnapping, forcible confinement and aggravated sexual assault, and one of committing an indignity to a human body. On November 3 he was sentenced to life with no parole eligibility for twenty-five years and declared a dangerous offender, which makes the sentence indeterminate.
He was never tried for Tammy Homolka's death. He was charged in connection with it in 1994, and the charges were still outstanding when the 1995 trial began; after the life sentence they were not pursued. Some later news reports describe a manslaughter conviction for her death, but the 1995 verdicts covered only the Mahaffy and French counts. In 2000 the Ontario Court of Appeal dismissed his appeal and the Supreme Court of Canada declined to hear it. In 2006 his lawyer disclosed that Bernardo had confessed the year before to ten further sexual assaults.
Two reviews examined how it had all gone so wrong. Justice Patrick Galligan's 1996 report to the Attorney General looked at the Homolka deal and concluded that, on what prosecutors knew in 1993, it had been justified. Justice Archie Campbell's Bernardo Investigation Review, released the same year, looked at the police work and found what he called systemic failures: the untested samples, the forces that did not talk to each other, and the lack of any system for managing a major case across jurisdictions. Ontario built its major case management system on his recommendations.
The videotapes were destroyed in December 2001, with the agreement of the French and Mahaffy families, so they could never be seen again.
Bernardo served his sentence at Kingston Penitentiary until it closed in 2013, and then at Millhaven, a maximum-security prison near Kingston. In May 2023 the Correctional Service of Canada moved him to La Macaza Institution, a medium-security prison in Quebec north of Montreal. The families learned about it only afterward, through their lawyer, Tim Danson. Ontario Premier Doug Ford said Bernardo should rot in a maximum-security prison, and the controversy contributed to Public Safety Minister Marco Mendicino's removal from cabinet that summer after it emerged that his office had known about the transfer in advance. A Correctional Service review concluded the move was sound and followed all applicable laws and practices, while conceding that the families should have been better informed. He stayed at La Macaza.
He first became eligible for parole in 2018 and has been refused at every hearing: in October 2018, in June 2021 and on November 26, 2024. At the 2024 hearing, held at La Macaza, Debbie Mahaffy read a victim impact statement and broke down as she spoke of trying to forget the horrors of her daughter's death. Bernardo told the board he had been abandoned and neglected by his parents, that his mother had been sexually abused, and that he had wanted to "pay the world back." "I have no excuse for what I did," he said. "I wanted revenge." A board member asked him how sexually assaulting and murdering other women amounted to paying the world back for what had been done to his mother. He said he was ready to step gradually back into society and would stay in Quebec. His own parole officer said he had adjusted well but was overestimating his progress while underestimating the risk he presented. The two-member panel deliberated for about thirty minutes and denied day parole, full parole and temporary absences, citing his clinical assessments, the extremely violent and serial nature of his crimes and his dangerous-offender designation.
His fourth hearing in eight years was set for October 20, 2026, at sixty-two, again from La Macaza. On September 21, 2026, Tim Danson confirmed that the board had postponed it to January 2027. The board did not say why, and a spokesperson said only that an offender may ask for a postponement at any point before or during a review. Donna French and Debbie Mahaffy have attended every hearing so far. Danson has asked that hearings for offenders like Bernardo be held every seven years instead of every two, unless something significant, such as a medical breakthrough, justifies an earlier one.
