Daughter appeals for witnesses five years after billionaire Toronto couple killed

Barry and Honey Sherman were found dead at home in 2017 in a case that shocked Canada but remains unsolved

The daughter of a billionaire couple whose unsolved murder shocked Canada's largest city has pleaded for the public to come forward with any evidence ahead of the fifth anniversary of their deaths.

Barry Sherman, the founder of drug giant Apotex, and his wife Honey, were found dead in their Toronto home on 13 December 2017. A realtor found the couple in the basement pool area of their home two days later, with belts looped around their necks and attached to a pool railing.
