When I was looking for potential matches for Evans wife "Elizabeth" and his daughter's mother I found something interesting.

Nellie Flickinger was last seen in 1979 when her unidentified "marine" boyfriend came and got her. She disappeared before and was found in Yuma, Arizona. I wonder how long she was gone for the first time. She wasn't reported missing until 2007.

the time-frame is inconsistent with Evans because he was living in Manchester, NH from 1977-1981, but the mill had gone through periods of shut-downs if I remember correctly so who knows. I wonder how often Evans traveled while living in Manchester.
I believe Evans picked his victims carefully, it wasn't until Jun that he messed up. Her family and friends becoming concerned is ultimately what got him discovered. I personally believe when he met Jun he assumed that since she was an immigrant maybe that her family was overseas?
Anyways, unfortunately I believe most of his victims weren't reported missing or weren't reported missing for a number of years.
With Denise, Disappeared in 1981, not reported until 2016. Evans manipulated her family which is why she wasn't reported.
These are examples of women I believe he targeted:
1. Young
or naive
or trusting.
2. struggling single mothers.
3. homeless
or transit
or travelers
I found a few cases that would be examples of someone vulnerable to Evans:
