A team of investigators hired by the family of Barry and Honey Sherman announced on Wednesday they will provide an update this week into the billionaire couple’s December 2017 murders.

An advisory released via Apotex Inc., the Toronto-based pharmaceutical giant that Barry Sherman founded in 1974, said the investigating team and lawyer for the Sherman family will hold a news conference at 2 p.m. at the Apotex office in North York on Friday.

Barry Sherman, 75, and his wife Honey, 70, were found dead in their Toronto mansion on Dec. 15. Autopsy results revealed they died by “ligature neck compression” and police classified the deaths as “suspicious.”

The family, concerned by media reports on the investigation, hired their own investigators to probe the deaths.

In its last formal update on Jan. 26, Toronto police said the deaths were a targeted double killing but no suspects were identified.

"Honey and Barry Sherman were found deceased in the lower-level pool area, hanging by belts from a poolside railing in a semi-seated position on the pool deck," Det. Sgt. Susan Gomes said in January.
