Finnegan Blake was a Petty Officer who attended Waverly University and was also the second victim of rapist/murderer Gunnery Sergeant Leeka. After Marine Sergeant Joseph Turner's body was discovered, NCIS suspected that Blake might have been responsible for Turner's death but they were later told that Blake had been missing since Friday night with no-one knowing where he was. As such, the revelations soon led to the team back to Leeka who was the one who had killed both Turner and Blake and was also raping Midshipman Ashley Simmons as well.
