Mary Greene was 34 when she was reported missing from Edgemere, Maryland, on December 10, 1966. Her disappearance was described as sudden and out of character given her established routines and close relationships, which prompted immediate alarm among family and friends.

Local law enforcement carried out searches of surrounding areas and worked with community volunteers. Family members distributed flyers, used local media, and joined public appeals while detectives interviewed acquaintances, neighbors, and relatives to reconstruct Mary’s last known movements. Despite those efforts and months of investigation, no credible leads emerged and searches failed to locate her.

Mary’s family has kept her case in the public eye through appeals and community events. If anyone in Edgemere or the surrounding area remembers Mary Greene or has information about her whereabouts in December 1966, please come forward.
