Toronto police say they are treating the deaths of Barry Sherman, 75, and Honey Sherman, 70, as a double homicide.
Gomes said the bodies were hanging by belts from a poolside railing inside the home, and the couple was found wearing their clothing in a "semi-seated position", CTV reported.
Police found no signs of forced entry on all access points to the home, she said.
According to a source close to the investigation, the conclusions drawn by a team of experts hired by the Sherman family cast doubt on the prior assumption that the couple's death in December had been a murder-suicide, indicating instead a double-homicide.
However, it was initially unclear whether the couple died by double suicide, homicide-suicide, or double homicide, leading police to initially classify the deaths as "suspicious". However, the couple's four children dismissed outright the suggestion and have since hired private experts to conduct an independent investigation.More news: Turkey says 14 killed, 130 wounded in operation in…
Police refused to discuss any information about possible suspects.
Police never said on the record that this wasn't a murder investigation, but they definitely gave that impression within 24-hours of the discovery of the bodies. For the past six weeks, investigators have been scouring the home, which was only released Friday morning to the family.
"Toronto Police are investigating, and I hope that investigation will be able to provide answers for all of us who are mourning this tremendous loss", Tory said. "Each of the three manners (double suicide, homicide-suicide and double homicide), the options provided to us, were all equally considered as the evidence presented itself".
"Legal complexities in some executions have been challenging given the litigious nature of Barry Sherman's businesses, in particular the search and seizure of electronics in Barry Sherman's workspace at Apotex", Gomes said.
"They were extremely successful in business, but also very, very giving people", former Ontario Premier Bob Rae told CBC.More news: The Potentially Life-Saving Feature Added in iOS 11.3
"The branded drug companies hate us". The thought once came to my mind, why didn't they just hire someone to knock me off.
"For a $1,000 paid to the right person you can probably get someone killed".
The Shermans recently listed their home for sale for almost C$7 million (£4.1 million).
Barry Sherman had been in an ongoing dispute with extended family over earnings from the pharmaceutical manufacturer, Apotex, that he grew into a mega-corporation after inheriting his late uncle's drug manufacturer.More news: A super blue blood moon is on the horizon
