Unsolved 1992 disappearance of mother, daughter, and friend from their home in Missouri
The Springfield Three refers to an unsolved missing persons case that began on June 7, 1992, when friends Suzanne "Suzie" Streeter and Stacy McCall, and Streeter's mother, Sherrill Levitt, went missing from Levitt's home in Springfield, Missouri, United States. All of their personal belongings, including cars and purses, were left behind. There were no signs of a struggle except a broken porch light globe; there was also a message on the answering machine that police believe might have provided a clue about the disappearances, but it was inadvertently erased.
