Andrew Klane is a crash reconstruction expert on the Commonwealth's witness list. He works at the same company as 3 of their other hand picked "experts." He's a former state trooper who oversaw the unit Trooper Paul was in, and presumably taught him everything he knows. He has been wrong on multiple crash reconstructions, including the death of an 87 year old woman who was run over by a car. He blamed her, but the woman's biomechanic son hired his own expert who determined that Klane's math was all wrong and the well connected driver was actually at fault. Of course State Police and the DA's Office refused to do anything about it. Andrew Klane isn't an expert, he's a hand picked hack who will do anything to back up the State Police narrative: https://tbdailynews.com/canton-coverup-part-498-commonwealth-crash-reconstruction-expert-andrew-klane-is-former-supervisor-of-trooper-pauls-unit-badly-evaluated-several-crash-reconstructions/
