Joan Risch was 31 years old when she vanished from her home in Lincoln, Massachusetts in the afternoon hours of October 24, 1961. With a bloody kitchen scene and confusing evidence left behind, police were never made sure of Joan's fate that day. She left behind her loving husband, two children, all her personal items. This case has never been solved, and Joan is still considered a missing person.  She would be 92 years old if she were still alive today.
