Tom Hanson: What was complicated about this specific case?

“Well I’m not so sure it was all that complicated but there was just a lot of evidence that needed to be gathered and carefully analyzed and obviously it’s a high profile case. So we need to know we are analyzing all of the evidence to the highest degree that we can,” Daly said.

Daily has reconstructed hundreds of accidents. When it comes to the Ravnsborg crash, Daily says at this point he can’t talk about specifics but he’s very confident they have a clear picture of what happened on the night of September 12th of 2020.

“The important stuff, yes we have it and we know it, and that’s all I can say about it,” Daly said.
