To be clear I am not saying that he was murdered by the Clinton's - but neither am I dismissing the possibility because their reputation has been in question for some time over these type happenings connected to those who worked for them, knew them and had some knowledge that could have been harmful to them, people who were going to testify against them and so forth. There was a mention in a news report that the Clinton's chef had given an interview stating that Hillary wanted all organic food served - everything had to be grown locally and approved as to where it was coming from - who grew it - etc. That is the only thing I've heard about him - discussing the Clintons - during his time as their chef.
He was hiking a 12,000 ft mountain, if someone wanted to kill him and fake an accident, its more likely he would have been found to have fallen over a cliff to his death, not drowned. Thats to random. He could have fallen and the force of the water even a couple feet deep could have disoriented him, pummeled him with small boulders. fast moving flood water is extremely powerful and just a couple feet can move cars.
