Narrative:

This was the last day of a 4 day trip (same captain). This was also the longest and most tiring. Captain had stomach problems on day 3 and should have removed himself then, but did not. He did not eat for over 24 hours at time of incident and was very worn down which I feel greatly contributed to this mishap, especially along with the long duty day. I was flying a visual approach to the runway and was at 2500 ft and only slightly high. I had called for gear down and flaps 20 degrees and the captain followed my request. 15-20 seconds later, I called for flaps 25 degrees (we land at flaps 30 degrees). The captain placed the flaps at 25 degrees but left his hand near the flap handle while looking outside. I called for flaps 30 degrees and the landing check. The captain then placed the right fuel control switch to cutoff, shutting down the right engine. I continued to fly the airplane to an otherwise uneventful landing. Attempt to restart was unsuccessful.
