Sheri Lynn Johnson was four years old when she, her 10-month-old brother Michael, and their mother Freda Denman disappeared from Independence, Missouri, in the autumn of 1974. The last known point for the family is believed to be about November 10, 1974; a TV guide left open to that date was found in the abandoned house. Their landlord noticed the family gone and reported the empty home in March 1975.

When police entered, Freda’s belongings remained, but the clothing of her husband and both children were missing and a small amount of blood was found on a cushion; tests at the time could not identify whose blood it was. The man known to the family as Michael Johnson was later identified as Henry Lee Harbison, a convicted offender with federal warrants and ties to a group called the Church of the New Song; some members of that group later claimed the family had been killed. The case was inactive until reopened in 2004 and remains classified as a non-family abduction with the family’s fate unknown.

If anyone knew Freda, Sheri, Michael, or Henry Lee Harbison in the 1970s, can you help with information?
