The billionaire philanthropist couple found murdered last month in their mansion outside Toronto were both homicide victims, police are now saying.

CBC Toronto reports that Toronto Police Det.-Sgt. Susan Gomes announced at a news conference on Friday that Barry Sherman and Honey Sherman’s deaths are being investigated as a double homicide.

“I believe that they were targeted,” Gomes reportedly said.

As CrimeOnline previously reported, the wealthy founder of a pharmaceutical manufacturer and his wife were found hanged by a railing next to their indoor pool on December 15. No suspects have yet been identified.

The announcement should put an end to speculation that Barry and Honey Sherman might have died as a result of a murder-suicide. Early in the investigation, multiple Canadian media outlets reported that unnamed police sources said investigators were looking into the possibility that Honey alone was a murder victim, and that she died in different location before being hanged next to her husband. Friends and family of the couple have insisted this theory was not plausible, and that Barry would never hurt his wife.

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. The uncle’s heirs reportedly believe they are entitled to a larger stake in Apotex.

Earlier this week, a source reportedly told CBC Toronto that investigators believe the Shermans were killed by multiple people.

At the news conference, Gomes said that police are interviewing an “extensive list” of people, but would not comment on any possible suspects.

At the time of his death, Barry Sherman was reportedly worth over $3 billion.
