The couple had died seventeen days apart in November 1965, leaving four orphaned young children: Paul Timothy, Jeffrey Andrew, Kerry Joel Dexter, and Dana Charles.

[25] In January 1972, Sherman and Ulster Limited sold Empire to the Quebec-based Canadian operations of publicly traded International Chemical and Nuclear Corporation (ICN) of California, for 57,000 shares (Valeant Pharmaceuticals).

The two produced the Cheetah Power Surge energy drink and started Steelback Brewery; when D'Angelo Brands went bankrupt in 2007, Sherman lost C$100 million.

The two had been introduced by a mutual friend, Cineplex Odeon co-founder Myron Gottlieb, who had met Rootenberg in prison following his conviction for fraud in the collapse of Livent.

[15] Even as his fortune grew, Sherman drove his cars until they reached an advanced state of disrepair; a friend worried that one, a Ford Mustang, was so decrepit that it was leaking carbon monoxide into the passenger compartment.

[38] On the other hand, Morton Shulman, a physician and former member of the Ontario Parliament who late in his life fought Sherman over drug development, called him "the only person I have ever met with no redeeming features whatsoever".

"[38] Attaran accused Sherman of crossing ethical lines concerning intellectual property rights to "fight as many as 100 battles at a time in court to challenge drug patents and make way for Apotex's generic prescriptions" with little end benefit to consumers.

"It was intimidating to come back from lunch and find an urgent memo on your desk saying you’ve got to get over to Federal Court because Sherman was at it again," recalled Michele Brill-Edwards, former Health Canada head of drug regulation.

One of Apotex's lawsuits, over the company's application to make a generic version of the antidepressant Trazodone, took thirty years until the Federal Court of Appeal ruled that the government had mishandled it.

Eventually Olivieri regained her position after years of her own litigation; the incident helped inspire John le Carré's novel The Constant Gardener.

In particular, they claimed that the garage, a structure with a tennis court on top and a basement lap pool and hot tub, was faulty; Sherman called it a "disaster".

He and his wife filed twelve separate suits against all the contractors; ultimately they would recover almost the entire estimated $2.3 million cost of building the house through favourable judgements.

[22] A partial draft of his unpublished memoir, called Legacy of Thoughts, was submitted as part of Sherman's motion for summary judgment in the lawsuit brought by his orphaned cousins.

[38] Sherman was targeted by the Canadian wing of the Jewish Defense League, a group on the FBI's terrorist watchlist, and had been sued by Israel's largest generic-drug maker, Teva Pharmaceutical Industries.

[22] At the time of his death, Sherman, legally registered as a lobbyist, was under investigation because of a fundraiser he had held for Justin Trudeau in April 2015, allegedly contrary to Canada's lobbying rules.

[22] "There is basis to conclude that Mr. Sherman is in breach of ... the Lobbyists' Code of Conduct as a consequence of his involvement in the organization of a fundraising event for the (Liberal Party)," according to Phil McIntosh, director of investigations at the Office of the Lobby Commissioner.

[49] In 2017, the Shermans decided to sell their longtime home on Old Colony Road in North York and move to a new house they were building in Forest Hill, closer to downtown Toronto, where many of their friends and business associates lived.

Plans for a replacement on file with the city called for a 16,000-square-foot (1,500 m2) house with features such as a central swimming pool with 41-foot (12 m) retractable skylight and living quarters for staff.

[22] Construction of the house, and Sherman's ultimately successful effort to recover legal fees from the Winters after their suit was decided in his favour, preoccupied the couple later in the year.

They put the North York home on the market, asking almost $7 million, at the end of November, even though construction had not started on the Forest Hill house.

[15] On the second anniversary of the case, the Toronto Star reported that the positions the bodies were found in nearly matched those of two 1970s-era "junk" sculptures of human figures posed sitting on speakers in the basement.

[55] Toronto Police Service had previously told the news media that there was no indication of forced entry into the Sherman home and that their investigation did not include a search for any suspects.

[64] In January 2018, the Toronto Star published an exclusive report based on anonymous sources from the family's investigation team who said that the deaths were murders: the couple was strangled by belts after their hands were tied.

[66] At the time, they would not discuss any possible suspects, but planned to interview everyone who had access to the home prior to the deaths via the lockbox that was previously installed by the real estate agent.

[67] In late October 2018, lawyer Brian Greenspan announced that the family had offered a $10 million reward in the couple's homicide investigation for any information that leads to the arrest and prosecution of a suspect.

[68] Police Chief Mark Saunders later told the news media that a forensic pathologist has been working on the case, in addition to over 50 officers, interviewing 200 witnesses and collecting over 2,000 hours of video surveillance from neighbouring homes.

While previous statements had suggested police believed the couple had been killed early on December 15, they now said the murders had occurred two days earlier, within hours of the Shermans returning home on the night of the 13th.

After telling Bloomberg that he'd been informed he was a "prime suspect" and consulting with his lawyer, Kerry Winter allowed that he had not only the motive to kill his cousin but the opportunity, since he was working at the time as a construction supervisor and could set his own hours.

In his interview with Bloomberg, he said "The worst thing that could have happened to Frank D'Angelo is Barry dying" and expressed regret that he had not been able to save a man he regarded as a close friend.

An Ontario Superior Court judge applied a "protective order" to the file, but the Toronto Star, a newspaper and media company in Canada, appealed and won.
