I think LE was on to her or at least had strong suspicions from the get go too. Hearing about his "alleged" Google search, interviewing her & looking around the house/yard the night Gannon was reported as a runaway, LS saying she didn't see him leave & didn't know which friend he was going to visit, seeing the bizarre missing flyers that LS made= red flags & suspicion. I'm not LE, but I'm a mom and I thought things didn't sound right when the story ran on our CO news Tues am. Look at her mannerisms, body language, and how she talked in that interview.......we all knew seeing that, do you think she was different when LE first spoke to her on Monday night? I think not!
I think LS threw a tantrum with AS on purpose because he had LH (the woman she was jealous of & despised) staying in their home. She probably was upset about this but it was the perfect excuse that she needed to leave the home. I'm sure at that point AS & LH were concentrating on finding their child, not a love triangle. If that saucer sized pool of blood was in Gannon's room (I think it was) are we supposed to believe that no one (not LE, AS, or LH) didn't notice it immediately on Tuesday? I guess it could've been concealed or covered somehow, but if your kid was missing wouldn't you carefully look around his bedroom for clues or to see if anything was missing? So I think that either AS discovered it on his own on Tues or LE pointed it out to him like LS said in the Crime Online interview. Regardless, I think it was found on Tues so they were on to LS for sure by then. Pure speculation, but I think LE had eyes on TS from this point hoping that she would lead them to Gannon.
