We have previously noted and commented upon the case of Raymond Davis.
By way of various sources, we have learned that Mr. Davis has been released from custody in Pakistan and has left the country. Apparently, this took place after the payment of some sum of money (one source states $2.3 million) to the families of the two men Mr. Davis shot. The United States Government denies payment of any compensation to the families.
Poorly edited NYT article here. Better edited, but less detailed and buried deep in the website LAT article here. WP coverage, which seems to be the best overall, here.
