The story up until this point goes something like this:
Sandy married Albert McCullough sometime in the 1990s. She then had an affair with his brother, Gary, ending the first marriage. In 1996, she married Gary. She and her three daughters then moved with the second McCullough to Missouri, where Sandy began an alleged affair with Kristopher Klemp. In 1996, after apparently planning to leave Sandy, McCullough went missing. (Upon request from surviving family members, McCullough was declared dead in 2005 .)
In 2003, Sandys daughter Lena Chapin, then 17, claimed Sandy had killed McCullough and recruited her to help dispose of the body (as seen in the episode "Missing Witness," Albert recorded this confession himself). She withdrew her confession after being contacted by policeshe and Sandy both lawyering up at this point. Three years later, Chapin also went missing. Sandy was then given custody of Chapin's child.
Sandy divorced Klemp in 2014.
Where is Sandy Klemp now?
As of 2016, Sandy Klemp was living in Mt. Vernon, Missouri. Local police believe she remarried and at that time continued to raise Chapin's son. Sandy, however, was not interviewed for the Netflix series. Her current family situation is unknown.
In an interview with TheWrap , Unsolved Mysteries co-creator Terry Dunn Meurer noted that Sandy could still be charged for murder. "She could still be brought up on charges if there was proof that she had anything to do with Lenas disappearance," Meurer explained. There is no statue of limitations on murder, she pointed out.
Until then, there are no other known leads.
