Human Factors
Air Carrier X was [on] landing roll. Thought they were going to make turn off onto Runway 22R. Aircraft never turned off the runway. Was distracted by other aircraft checking in. Thought I had enough space for second arrival. When I looked out window saw second arrival touching down. No alarms for runway occupied were sounded. [Need to] verify aircraft makes turn off on runway.
Tower Controller failed to note that a landing aircraft missed the assigned runway turn off; allowing a second aircraft to land without appropriate separation.
