If she was cheating or up to no good cell phone records would prove her last night rendezvous and im sure the late night person would have been contacted. When you cheat using a cell phone or go off to party there is always a trace, a record of late night cell records ( pings of phone activity of leaving late night in the past). I wonder if she has a google (gmail account) you can go to the settings and look at location history, search history. I've had a cheating bf I do better investigating than the FBI. You can log in gmail using laptop and track a persons every move using gps. This guy constantly gives an alibi. When question who she was at Walmart with his answer "I wasn't there" she didn't ask you that. Naturally you know who was with her at what time now. He then states two kids were at home not just two yr old. Where was that child? Surely they would ask where is mommy the next day. No man wants two kids for the 4th one not being your own. Men don't always just throw something in a bag for a kid. They are going to a campsite, where is the bug spray ? Sunblock? That diaper bag is an important clue. The car seat? Was there two of them? Moms don't take off for awhile that late before a holiday family event the next day. I'm 32 and have a 2 yr old it is very exhausting this chick has 5 kids.. Think about it! She showed the house ( has that been confirmed) got home ..now what? You don't fall off the radar just like that. That phone she was playing on will hold clues, cell phones use data when in use. I hope all that has been looked at. Last cell activity etc..he said at 7:30 they left but never going into where they went. Who saw them. No wonder he failed a lie detector NG called him on the spot with questions that got him tongue tied. Who thanks someone for asking a question or bringing a question up. This guy was calling out cops by their name ( shout out to my friends who I need on my side). Dude is a flake!
