I find it hard to believe that people are so willing to discount the stories of 2 different people who saw just about the same thing, but will speculate all over about possible scenarios of Lisa's passing in that home.
There is nothing to support that however, There are 2 people that saw basically the same thing hours apart.
If they interviewed the woman 4 times, They are looking into it, I just wish they would put more out there and come out daily and say, "KEEP LOOKING FOR LISA.. we are looking into every possibility, But we need to be looking for a live baby NOW!" They can work on their other theories behind the scenes But I believe a lot of people may have stopped looking for her because they think LE has something on the parents.
