Narrative:
Flight xyz, while taxiing to gate after landing, ramp agent advised me that the aft stairs were open and hanging down. After blocking in, I went down onto the ramp to take a look. The stairs were hanging down about 2 ft from the closed position and it appeared to me that they did not hit the ground during operations. Prior to departure, I had maintenance comply with MEL for aft stair warning light inoperative. Mechanic's tools were also found on the stairs where they were left prior to departure. Callback conversation with reporter revealed the following information: the reporter stated the aft airstair warning light was on continuously and was in the process of being deferred per the MEL. The reporter said the MEL requires the airstair up latches be checked prior to departure for being up and locked. The reporter stated after landing the airstair unlocked and hung down about 24 inches.
