Missing Family

I had a family member go missing around 1982. He was last seen renting equipment to presumably go out on Lake Washington. Half of the equipment was found, the other half and him missing. He would have been in his 20s at the time, taller male.

If this rings any bells for people, please let me know. DNA tests have been done on Ancestry for relevant family members but no matches.

The case was effectively unsolved, though death was assumed.
