I'm trying to wrap my head around this 'person of interest'. Two of our largest libraries in the area frequently have homeless persons using them to read while staying warm in the winter or cool in the summer. This guy doesn't look a lot different from some of them when seeing him briefly from a distance. I don't see enough to lead me to believe he has any difficulty walking and even if he does it could be a temporary injury like a sprained ankle or knee so for someone who knows him but hasn't seen him recently that could be distracting. In fact, thinking about when I go to the library in these Covid-19 times - with everyone working from home - I don't dress a lot differently than him. Tactical trousers (similar to cargo trousers) or old khaki slacks, running shoes, T-shirt and a old jacket. I find myself wondering if I leave the library on a day when a person goes missing, why would I be on video as a POI?
There is something more here that has set this guy apart for LE. His timing upon leaving the library? Where the staff saw him in relation to where Raelynn was in the library, maybe in particular what he did when she entered? Did he talk to her in the library? Are was he merely the only adult male in the library when Raelynn was there? Are there additional CCTV cameras in the library that capture what has LE interest? Something bothers me about LE wanting to track down someone who, based solely on the video, would not attract any attention at any other time.
