The son of a billionaire couple murdered five years ago has tripled a cash reward for information about the unsolved crime amid frustration over a lack of progress in the investigation and deep rifts within the family.
Barry Sherman, the founder of drug giant Apotex, and his wife, Honey, are believed to have been killed 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.
