Was David Lovely’s disappearance ever featured on UM?

David was 19 in 1985. He and his family were moving across the country (CA to MA). His family was driving a moving van and David was traveling on his motorcycle. They were meeting at rest stops periodically. At some point, his motorcycle broke down and he got separated from his family. He called his aunt and said a biker helped repair the bike, but this was the last time he was ever seen or heard from. He went missing in WY.

I have searched this forum by name and key word (motorcycle, moving van, Wyoming) to no avail. Am I misremembering what show this case was featured on?

I guess this case was never featured, as no one else seems to remember it. It’s also not included on Unsolved.com or the wiki. I must have imagined the segment.
