Obviously making sure people dont over stay their visa is way too hard. Its not like they can make a computer system that notifies local officials that they need to check on the person...
Anyway, this is obviously a cover up. Sending a witness to a murder away? Thats rediculous. At the very least they should be issueing a temporary visa of some sort until everything is wrapped up.
To climb the mountain, you must believe you can.
