You know, I had an uncle that disappeared from our family for, like, 30, 35 years.

We kind of had an idea where he was.

they were last seen and when the car was found the following morning? And why did the lead on the

case for the Bismarck Police Department, Detective Tim Turnbull, feel that the most likely explanation

was that Sandra and John entered the water on that dark, cold night and drowned.
