Narrative:

During post landing and taxi in; I commanded the shutdown of the number 2 engine. Upon reaching the gate and setting the parking brake; I said 'brakes set; pressure normal. Shut down number 1.' I saw; out of the corner of my eye; the first officer move a start lever. I assumed the first officer shutdown the engine so I continued with my parking flow and made a short call to maintenance to report a write up. I then called for the parking checklist. The second step on the checklist is checking that the start levers are cutoff. I found both start levers in the run position with the number 1 engine still running. I immediately positioned both start levers to cutoff shutting down the number 1 engine as I was concerned about the safety of ground personnel. The number 2 engine was not running at the time. The first officer had mistakenly return the number 2 start lever to run instead of shutting down the number 1 engine. No injuries occurred. Upon debriefing the event; the first officer said he understood my command but just made a mistake.
