Chris O'Brien is who you want to go to if you want to talk cattle mutilations. Finally released his
mammoth mutilation book last year which contains his research from a couple of dozen years of his own investigation:

He had so much material that he just presented data, and not much analysis, and still covered more than 500 pages. At least that's what I understand; I haven't yet read it. He's said he's coming out with a follow-up book that interprets everything. Or tries to.
Paracast episode about a year ago about the book with his mentor, David Perkins:

Good Radio Misterioso show with him:

(fyi Radio Misterioso is my favorite podcast, it's kind of an unplugged free-for-all with Greg Bishop...who is the guy you want to listen to if you want to talk about Paul Bennewitz or Richard Doty).
