Police in Canada said Wednesday they had identified a person of interest in the high-profile murders of a billionaire couple three years after they were found dead in their Toronto mansion. 
Barry Sherman and his wife Honey were found hanging by belts from a railing next to a swimming pool at their Toronto home on December 13, 2017.
Police estimated that the couple had been dead for at least two days before the bodies were found. They are treating the case as a targeted double murder. 
‘The Toronto Police Service can confirm that a person of interest has been identified but not arrested,’ a police spokesperson said.
Barry Sherman founded Apotex in 1974 and turned it into one of the largest generic drug makers before stepping down as chief executive in 2012.
Avid philanthropists, Barry and Mary Sherman were known for their donations to hospitals, universities and Jewish organizations.

The case was initially treated as murder-suicide, before police – under pressure from his family – said they believed it was a ‘targeted’ double murder at their home.
Investigators said Barry and Honey were found dead in the lower-level pool area, reportedly hanging by belts from a railing on the pool deck and wearing their clothing.
Police ruled the deaths of the billionaire couple a double-homicide after
a post-mortem examination determined the Shermans died of “ligature neck compression.”
It was also determined that the couple likely died two days before they were found on Dec. 13, 2017.
The Sherman family has criticized police handling of the deaths and hired a private investigator of their own to look into the case. The detective completed the work last year but gave no details to the public. 
Cops said Wednesday a person of interest had been identified but not arrested.

Barry Sherman was known for litigiousness and aggressive business practices as he developed Apotex, which had a global work force of about 11,000. In ‘Prescription Games,’ a 2001 book about the industry, he mused that a rival might want to kill him.
The couple was among Canada´s most generous philanthropists, and their deaths shocked Canadian high society and the country´s Jewish community. 
They made numerous multimillion-dollar donations to hospitals, schools and charities and had buildings named in their honor. They hosted Prime Minister Justin Trudeau at a Liberal Party fundraiser in 2015. 
Barry spoke of signing up to The Giving Pledge, shortly before his death.
The campaign, spearheaded by Warren Buffett and Bill and Melinda Gates, sees the world’s richest people promise to give away ‘the majority of their wealth to philanthropy,’ massively cutting the amount their families would inherit in the process. 

The day after the bodies were found, some prominent news media outlets quoted unidentified police officials as saying the deaths appeared to be a murder-suicide. 
That upset the couple´s four adult children, who then hired their own team of investigators and a pathologist, who conducted second autopsies on the Shermans.
Police later said publicly they believed the Shermans were murdered.
Friends and family say the couple had been making plans for the future. They had recently listed their home in Toronto for 6.9 million Canadian dollars and they were building a new home in the city.
Sherman faced legal action from cousins who said they had been cut out of the company over the years.
A judge dismissed the claim just months before the couple was found dead.
