COLD CASE MURDER London woman hopes $50K reward will lead to arrest of sister Donna Awcock's killer: Donna Awcock, a former resident of Cheyenne Avenue (now 88 Oakville Avenue) offered her services as a baby-sitter for an evening, walked a short distance to a local neighbourhood strip mall variety store, and was never heard from or seen again. Then her body was discovered by a passerby. Her family have been working diligently to keep Donna's case open all these years since her tragic demise. I learned about this sad case from people who were members of a vigil party who gather in the parking lot next to the building Donna lived in, and light candles in her memory.
