Narrative:

Received an RA while turning final to runway 35L. TCASII showed traffic behind aircraft (4 moving to 5 O'clock position) when RA received. Never saw the traffic visually. Complied with RA and after about 5 seconds, 'clear of traffic' was announced. I spoke to the tower supervisor, who spoke to approach control (we were technically in approach airspace) and he said that they had monitored the event and since visual separation criteria was being used, they had no issue with this event.
