Mr. Harris was not a lieutenant.
It’s the name on his birth certificate.
You are correct.
Leiutenant Quarles Harris Jr. (September 26, 2010)

and note spelling of his first name. (Leiutenant)
This is typical of the agency. My last day overseas at State, I had to pull the Navy DAO aside and teach both the young Army 0-6 that you don’t wear novice jump wings under your pocket and your Master Parachutist Badge above your ribbons.... I told’em he would blow his “cover”. Another thing, civilian civil service positions are accorded a certain level of status under the Geneva Convention(s), and a G-11 converts to 0-5 but I’d peg a GS-11 at E4/5 tops. So this 0-6 was probably a GS13 or FS3....
