Canadian police do not share homicide information in their investigations. Greenspan's hope that the two investigation teams would do so has not happened and it''s apparent that it never will. Greenspan noted that a few American police forces have accepted help from outside investigators, and that it has never happened in Canada. That is Canadian LE protocol, and LE not sharing information with Greenspan does not suggest that their reason is because his client(s) are a suspects. The murder/suicide theory was debunked immediately by the children. It would be interesting to know if one kid thought it was likely a m/s and didn't want to hire Greenspan.If that never happened, then none of the kids are a suspect imo.
