I just watched Dr. Wolf's testimony. I imagine Alessi decided after his direct testimony, that there was not much to disagree with because Dr. Wolf's testimony about HOW it happened, was still not definitive IMO
Even Dr. Wolf said that an object more likely than not would have shown a depressed skull fracture. More likely then not is not definitive. Again, JMO
His experience with cold weather falls, drunks falling, etc was from his time in Minnesota. I live in Canada, but we have similar weather to Minnesota... I have enough life experience with cold weather, snowing, blizzards to understand that the way they are saying a cold hard ground on that night may not have been as cold and as hard as they say. Again JMO And I'm sure the jury has some experience with that as well
