Narrative:

BE20 was issued a climb to 5000 ft on departure and was issued traffic southwest of his position at 6000 ft. When the aircraft was climbing through 5700 ft I observed he had climbed above his assigned altitude. Supplemental information from acn 513443: BE1900 was on the granm four arrival at 6000 ft. I issued traffic 12 O'clock position, 6 mi, 4400 ft for 5000 ft. I noticed BE20 climbed above 5000 ft yelled to departure what was the king air doing. I issued traffic again to try to get visual separation. I turned BE1900 to a 090 degree heading to avoid traffic. The conflict alert did not alarm. The departing BE20 busted his assigned altitude of 5000 ft.
