I have been reading and thinking about this case. To me...the mothers' panic may be because the 23 year old was also missing from the house when he was usually home. She may have had a very good reason to suspect the worse. MOO
That is a very good point that I hadn't thought of and hadn't seen here...She may have seen the 23 yo the night before (or not) in the home and now both he and Celina aren't around and her mind starts going down a very scary road...
