May Mah was last seen in Toronto on the evening of Wednesday, October 14, 1981. She was observed by her nurse at about 9:00 pm and has not been seen since. May was described as a woman of Asian descent with a fair complexion, short wavy black hair, about five feet tall with a heavy build.

The Toronto Police Service was notified and an investigation opened, but information about her last movements and what happened afterward is scarce. There is little public detail or media coverage from the time, and the case remains unresolved and cold.

If anyone knew May, lived near her, or has information about her whereabouts in October 1981, please come forward with anything that might help.
