That sounds correct regarding the spiderweb of ownership changes for the mother’s house. Warner’s cryptic remark about the basement of his own house will have everyone thinking “Silence of of the Lambs” until we find out what it actually means.
Swing undoubtedly holds the answers to some of this mystery and probably has told investigators. Doesn’t mean that we will get to know how and why she is caught up in this mess. That’s going to take reporters snooping around and getting people to talk.
I am going to guess that he built or customized the basement for her hobby, whatever that might be or created a game/play room for her child.
I wonder what happened to his dogs?
