Narrative:

Upon arrival at the gate; shutdown checklist was followed. Captain completed post-flight walk around and I left the aircraft. After I returned; captain mentioned that during the walk around; the #2 engine appeared to be partially running with engine fuel lever in shutoff position. Captain said the inter turbine temp (itt) was slowly climbing when he got back to the cockpit. Dispatch and maintenance was then contacted. Engine was eventually shutdown. There was no evacuation or injury to passengers or crew. I was not onboard the aircraft and never saw any of the indications the captain mentioned about the engine. At my airline; the captain shuts down the engine at the gate while the first officer (me); reads the checklist. It is my assumption that a mechanical failure of a fuel shutoff valve might have caused the improper shutdown of the engine. A safety report was individually submitted by the captain and I after this incident.
