Narrative:

M20P departed runway 35 with an on course heading of 335. A SR22 departed runway 17 on heading 020. After being switched to departure; the M20P started to turn back into the departure corridor and the TRACON controller stated that he was turning back northwest bound. At that point I turned the SR22 to a 090 heading to ensure separation. The M20P continued to fly erratically and I turned the SR22 to a 120 heading to further ensure separation then switched him to departure. At that time the low altitude alert began to alarm and I started to visually search for the aircraft. I observed him descending out of the clouds in a steep right turn. At that time using the override line I heard the pilot state that he having problems; needed help and wanted to get down. He was then switched to tower. When asked to say intentions the pilot stated that he needed to get down; I then cleared him to land on any runway. I then proceeded to clear multiple vehicles off of runway safety areas. I then saw the M20P on final and cleared him to land. He then landed and rolled out with no incident. This emergency situation was due to pilot disorientation.
