"....Again, how can you be sure - you don't have the info LE has...."
Every news agency on earth is digging into this man's past, and so far, no one has found that he was in Colorado at the time of the murder.
How true are the reports that he was waiting for a "sex change" operation into a little girl?
Then why is he being brought over? An alibi check would be the first thing LE would do.
