My latest theory is this and is subject to change as more information become available. I still believe this mom did not not hurt her baby or give her to someone. However, I believe one or both of them know something and hopefully, that information was given to LE. The parents were giving interviews and communicating with LE until the day when something changed and they quit talking. What if -- LE gave them some information that they refused to accept at that time such as baby Lisa was probably no longer alive or had been taken for other unimaginable purposes? Would they want to believe this and might be angry at LE for bringing it up? Possible. Maybe LE mentioned a name that they refused to believe could be potentially responsible and the parents didn't want to believe it. Possible. Maybe LE believes baby Lisa is no longer in the area and national media is a better way to go. Possible.
Many have said they'd be out searching, speaking to media, etc. and wouldn't care what people thought about them. Maybe they're following LE's lead and doing what they were told to do and if that's the case, they really don't care what people think. Just another way to look at it. JMO
