Police have identified a person of interest in the high-profile murders of a Canadian pharmaceutical billionaire couple.
Barry Sherman, who founded generic drug manufacturer Apotex Inc, and his wife, Honey, were found dead at their Toronto mansion on December 15, 2017.
Police Constable Jenifferjit Sidhu confirmed a report by the Toronto Star that a person of interest had been identified but said they had not been arrested.
The couple were among Canada’s most generous philanthropists and their deaths shocked Canadian high society and the country's Jewish community.
Mr Sherman, 75, 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 made numerous multimillion-dollar donations to hospitals, schools and charities and had buildings named in their honour.
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.
The reports 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.
