The married Canadian billionaires who died in what cops labeled a bizarre murder-suicide were actually killed by bitter business rivals, sources said.
Private investigators hired by the family of Barry and Honey Sherman believe evidence at the scene of their grisly Dec. 15 deaths proves the murder-suicide ruling is bogus — and they revealed the potential motive for the horrific hit.
Well known in Canada, Barry made billions in the pharmaceutical industry — often at the expense of his competitors.
"Barry would often wait for patents to expire, and make a generic drug to undercut other companies," said a source close to the investigation.
"That would infuriate his competitors, and we're talking about a lot of money — enough of a motive for murder."
Referring to his competition in the gripping 2001 book Prescription Games: Money, Ego and Power Inside the Global Pharmaceutical Industry, Barry said flatly: "They hate us."
Shockingly, he even predicted his own awful fate in the same book.
"The thought once came to my mind, 'Why didn't they just hire someone to knock me off?' For a thousand bucks paid to the right person you can probably get someone killed. I'm surprised that hasn't happened," he told author Jeffrey Robinson.
The couple's bodies were found inside their $5.4 million Toronto mansion with belts around their throats, and tied to a railing adjacent to their basement pool.
Cops quickly concluded Barry, 75, killed his 70-year-old wife, and then hanged her on the railing before hanging himself.
But inconsistencies obtained from leaked police files now indicate their corpses were moved by contract killers to set up that murder-suicide scenario.
According to an insider close to the investigation, the family's PIs discovered signs that both victims' were hogtied together at one time.
But neither victim's hands were tied when they were found hanging from the railing — suggesting their bindings were removed after they were strangled.
What's more, the investigators believe the way the couple was choked to death is inconsistent with the manner in which the bodies were hanged.
They believe the husband and wife were more likely strangled with the belts, which were then tied to the railing to create the appearance of a hanging.
Honey's face was also covered with cuts — and when investigators examined bloodstains on her clothing, they concluded her body was lying face down for some time before it was hanged.
"This was no suicide pact," the source said. "Barry had enemies — and this is their grisly handiwork."
