I came across this post: http://np.reddit.com/r/JusticePorn/comments/1s4av0/suspect_of_fatal_hitandrun_followed_by_an/cdu77nn

Which linked to quite an interesting set of research papers. Does anyone have any insight into how valid this research is?

EDIT: The linked post has been removed. I should have saved it. Thanks for the links to the info. This is exactly what I was looking for.
