Summary based on the NamUs case record (MP31687) and 20 other sources
Joan Risch, a 30-year-old homemaker and mother of two, disappeared from her home in Lincoln, Massachusetts, on October 24, 1961, under mysterious and unsettling circumstances. That morning, she completed routine activities, including a trip to the dentist with her daughter. After returning home for lunch, she left her two-year-old son in his crib for a nap and her four-year-old daughter playing outside with a neighbor. By the afternoon, she vanished.

At around 4:00 p.m., Joan’s daughter returned home and found the kitchen in disarray, with what she thought was "red paint" on the walls, which turned out to be blood. A neighbor, Barbara Barker, alerted the police after verifying the scene. Investigators found smears of blood, an overturned table, and a phone ripped from the wall. A trail of blood led outside to Joan’s car, but there were no clear signs of what had happened to her.

Despite extensive searches and witness reports of a woman matching Joan’s description, possibly injured and dazed, walking along nearby roads, no definitive clues were found. Some theorize that Joan may have staged her own disappearance due to unhappiness, while others suggest a potential accident or crime. Intriguingly, Joan had checked out multiple books about disappearances and crimes from her local library in the months leading up to her vanishing, adding to the speculation that she may have planned her own disappearance.

Joan Risch's case remains unsolved, and no trace of her has ever been found. Various theories persist, but the mystery of her disappearance continues to baffle investigators and the public alike.
