A biomechanics expert says he wants a criminal trial where witnesses can be cross-examined about Amy Wensley’s death because he is “95 per cent” certain she did not take her own life.

Dr Ackland — who analysed the biomechanics of Amy Wensley’s death — said there were “about 20 things” in relation to the death which looked “unusual and extraordinary”.

“There was so much inconsistency in the witness statements and in what people had said had occurred and the evidence,” he said.

“The whole thing from the start did not ring true. Not much of the witness statements information made sense to me.

“The only thing that made sense was the report of the attending uniformed officers who were the first people on the scene apart from those witnesses.”

“There is a lot of politics around this . . . the longer this goes on, it troubles me more and more that I believe that an injustice has been done, and it’s part of the reason why I’m sitting here today,” he said.

“I just get the feeling that the evidence hasn’t been weighted in the best way possible to get Amy justice.

“I think it can progress if those various players who were witnesses on the scene have an opportunity to present themselves and be cross-examined and interrogated.”
