How public input helped.

The public contribution
A citizen contacted Butte County investigators using Doe Network information. [1]
Read the documented outcome
Detectives pursued the proposed connection, and a family DNA comparison established Marvin’s identity in 2020. [1]
Here’s where you come in
Can you trace the citizen’s inquiry through the detective work to the DNA comparison?
Compare the dated sources and keep the public contribution separate from the work that confirmed the result. If a source leaves something unanswered, leave that question open.
Keep the exact links, your own notes and questions together in a Research File in Almost Solved. You can return to the record as you find more information.
