I appreciate yesterday's basement discussions; I have read them but not posted about the issue (no personal experience). For me, they were helpful in that:
1. If this is the "bedroom" in which Wendell Noyes claims "they" last saw Celina at the computer at 9 pm the night before she disappeared, it could be a crime scene. Depending on on the condition of the basement and whether or not Celina felt comfortable in it, it could be indicative of how Celina was regarded in the home.
2. Whether it is or isn't the room where Celina was last scene, the basement might have a door that would allow an unwitnessed exit from the house.
So, imo while it's not yet known whether the basement is an issue at all, it could turn out to be important. For now, imo, we don't even know for sure if Celina and/or her sister were actually sleeping in the basement on an air mattress. Their father, AL, originally said everything was good at the house, seemed loving, it appeared the girls were happy and well cared for by their mother and father (referring to Wendell Noyes). After Celina's body was found, he said it bothered him and he found it crazy that the girls had been moved from nice bedrooms in the house to an air mattress in the cellar/basement (by decision of those he would not name) when Kevin M moved into the house.
Since we have no statements from anyone living in the house, it's possible that Kayla told him about the sleeping arrangements during her visit with her father after Celina's body was found, or AL had known that the girls were in the basement for a year and it seemed more hinky to him in hindsight, or if he may have gotten misinformation about the sleeping arrangements as the focus on KM living in the house took off and people started talking and speculating more about it. Will be interesting to (hopefully) find out what LE and/or those living in the house have to say about the relationship dynamics, the activity in the house, and where Celina slept and was last seen.
JMO...
