Grieving relatives of Barry and Honey Sherman have sought the help of a legal heavy hitter to conduct their own investigation into the couple’s deaths.

Toronto lawyer Brian Greenspan confirmed to the Star Wednesday night that he is offering informal help to the family of the billionaire philanthropist and his wife, whose mysterious deaths have shocked the city.

“I have been serving as a resource person for the Sherman family and Barry and Honey were people who I admired and respect,” Greenspan said.

“The family did contact me to be a resource person for them and I’ll fill that role.”

Greenspan said he had no further comment on how the investigation would be conducted or when it will begin.
