Human Factors
After deplaning the aircraft in ZZZ the Captain was informed by the Captain of the next crew that the Number 2 engine had been left running. Maintenance and weather delays caused our last leg of a 4 leg day to arrive in ZZZ two hours late and within 30 minutes of timing out. In a rush to hand the aircraft over to the waiting crew we ran the parking checklist and we did not verify that the engine was shut down on the EICAS during the parking checklist. The Captain only visually confirmed that the start/stop selector was in the off position and due to the thrust lever being positioned slightly advanced the engine never shut down.The Captain receiving the aircraft notified the previous Captain that the engine had been left running and shut it down. I was informed of the event the next morning upon arriving at ironically the same aircraft.Lack of confirming what is said during a checklist is correct and time constraints to hand the plane off to the next crew. Confirm what the captain says during the checklist is correct instead of just accepting it.
EMB-145 flight crew reported leaving one aircraft engine running at the gate when deplaning.
