Did the Clintons kill Klaus Eberwein to cover up Haiti Clinton Foundation Corruption?

A very unusual suicide happening days before he was to testify before the Haitian Senate Ethics and Anti-Corruption Commission. He also had friends reporting that he was in good spirits and planning on opening a restaurant. He also said he feared for his life because of his harsh criticism of the Clinton Foundation. This could be untrue but with so many stories like this around the Clinton's I find it hard to believe that they are all coincidences.
