Does anyone remember the case of 3 women--2 were mother and daughter, the other was the daughter's friend, who went missing in Springfield, Missouri approximately 15-20 years ago? I don't know names or any other details other than the girls had just graduated from high school, I think, then went to a party, came home (one was spending the night at her friend's house) then they all just vanished. I saw the story on 48 Hours and it has haunted me ever since but not knowing names, I haven't been able to follow up on it. Does anyone remember this? Please let me know if you do.
