A Canadian billionaire and his wife have been found dead at their home in Toronto in circumstances that police described as "suspicious".
The bodies of Barry Sherman and his wife Honey were found in the basement, reports said.
Mr Sherman was the founder and chairman of pharmaceutical giant Apotex, which sells generic medicines around the world.
He was one of Canada's richest men and a prominent philanthropist.
Police gave few details and did not confirm the identities of the deceased. However, they were named locally by friends and by officials who reacted with shock at the news.
The couple had four children.
Mr Sherman founded Apotex Inc in 1974 and the firm says it is now the seventh biggest drug maker in the world, reports BBC.
Forbes magazine puts Mr Sherman's personal net worth at $3.2bn (£2.4bn).
