Narrative:

During a busy arrival push, controller vectoring several aircraft to ILS 32. Air carrier X was on downwind at 6000 ft and commuter Y was straight in on ILS at 6000 ft, slowed to 170 KTS. X was given turn north for final and not descended. Controller anticipated a reasonable turn. To be honest there was no doubt in my mind that separation would be maintained. Another aircraft checked in on frequency at this time, diverted my attention, because it was an unusual altitude, reported in at, and before I got back to my final, air carrier X and aircraft Y were on converging courses and I had to turn aircraft Y off localizer and descend aircraft.
