After reading the documents about how the case would have been argued, one point remains forefront in my mind: the difference in timeline with the two victims. Jesse was unaccounted for between roughly 9:30PM and 11 on the night that Morgan was abducted. With Hannah, he abducted her shortly after 1AM, but he was not where he should be at 7:30AM the following day, and was off line for several additional hours.
The bodies were found roughly 18 miles from abduction site, so maybe a 20-30 minute drive one way.
That suggests that he spent about 40 minutes with Morgan, and hours with Hannah. Given the cuts to Hannah's jeans, and the injuries to her face, I think she put up a fierce struggle.
What is tremendously sad is that so many people observed Jesse with Hannah, recognized that something was wrong, and yet no one stepped in to help.
Add to that the numerous people who were targets of his way over the top sexual/physical advances throughout the evening as well as those who observed his behavior and did nothing to report it.....
