Last night, I watched a new episode of Cold Case Files and it documented the May 1992 disappearances of Wendy Camp (who had MS), her daughter Cynthia Britto, and sister-in-law Lisa Kregear. The episode, titled “Sooner State Nightmare”, mentions the fact that the case was on UM (the UM segment originally aired in October 1993).

Go to the UM wiki link below for more details on the case.
