Rodger Moore died on 2/6/17. I was just notified of this, so sorry for the belated notice.
His obituary is here. The obituary says:
He was employed by the U.S. Military Court of Appeals and retired as a trial attorney for the Tax Division of the U.S. Department of Justice.
Rodger served in Refund 2 while I was in that section (1974-1977)
and, as I recall, was an old-timer (47 years old). I am not sure what his trajectory in DOJ Tax was other than that.
