Unfortunately, nothing new about Michael here, but this local article from February mentions him and lists some interesting stats:
Rogue Valley News, Monday 2/8 – Oregon Has Third-Highest Rate Of Open Missing Person Cases In USA, White City Man Sentenced for Illegally Poaching in Crater Lake National Park For Years - Rogue Valley Magazine
"NamUs, which helped find Davis, says there are currently 16,025 open missing person cases in the U.S. Of those, Todd Matthews, NamUs’s communications director, told a KATU reporter 60 percent are men.
“It’s harder to get news media to cover a missing male than it is a missing female,” Matthews said. “They’re not considered so much as a victim.”
A
study by the website VivintSource found Oregon ranks No. 3 on a list of states with the highest numbers of open missing person cases per 100,000 people.
Washington ranks No. 4.
Matthews said the top five states do not require law enforcement agencies to use NamUs. Only Tennessee, New York, Illinois, Michigan, Oklahoma, and New Mexico require agencies to use NamUs in missing person investigations."
Edit - Alaska and Arizona are numbers 1 and 2 respectively.
