IMO For adults who are not where they are supposed or expected to be. A short delay before calling 911 is not unusual or inherently suspicious. We know now that something was very wrong and that every minute matters in an abduction, but the family didn’t have that information at the time. In many cases, family or friends first check the home, nearby areas, and routine locations before calling LE. Evidence that LE discovered in or around the home can easily be overlooked by loved ones who aren’t viewing the scene through LE lens. People also hesitate because they don’t want to overreact, embarrass the person if they turn up, or feel like they’re wasting ER resources. The delay in this case doesn’t strike me as suspicious. I actually have a tremendous amount of sympathy for families of missing people when this happens. No one beats them up more than themselves. IMO
