Actually, she has usually been brought up during Q&A with a representative of the Police Department. Basically, the response is that it is an ongoing investigation in which the person is not directly involved.
However, I could tell by audience reaction (and conversations outside of the formal meeting) that the vast majority of attendees are aware of the case.
I have had multiple experiences which make me believe that residents of Sun City Roseville are particularly aware of Susan's disappearance. I would expect this to be the case, as there is likely cross fertilization between different clubs and groups, and there are a lot of people who golf, bike, walk, and eat at the
Timbers, etc.
Yes, I would guess that less than 1% of the population would attend one of these regular meetings during the year (while a larger number participate in awareness and recreational activities sponsored by the Neighborhood Associations).
Honestly, initial outreach by the Police Department to the public in the local area was fast, repeated, and by a variety of communication channels. If anybody had any knowledge about Susan's disappearance, they probably have already shared the information with the authorities (or they don't plan to).
If Susan is wandering around in Roseville, there are a very large number who have seen her picture.
