There is no evidence but I suspect these “suicides” had help. Not too hard to find a belt or scarf to tie around the neck up an unconscious or catatonic person thereby creating plausible deniability.
First ones I remember where that weathy Canadian couple. Same M.O. tied up to a railing with their own belts. Then the chef and the clothing designer. ALL OF THEM had Haitian and/or CF ties directly.
Again this fits a pattern of getting rid of anyone suspected of spilling the dirt on the Clinton crime syndicate.

Hanging seems to be a preferred way to get rid of potential witnesses. Remember the Washington Madam, her appointments secretary, and one of the Kennedy wives. All were hanged.
