I really don't know.
She supposedly went in and went to bed at 10:30, according to her. I would assume that's when she put the boys to bed. She also said at one time that she went on the computer. You can send messages to people's phones via e-mail on the computer. We don't know what LE knows about what activity happened on the computer that night. We don't know if Jersey had a phone. I just think with the boys saying they heard tapping noises and the screen on the window being pushed out, that the phones could have been passed out through it.
To me, that means there is a possibility that DB contacted Jersey and told him to come by and get some phones. He could have unknowingly took some phones that are now being tied to a missing baby. The 11:57pm and other attempts could have been made by him while he was possibly squatting in Watson's house. We aren't told when the internet attempts were made on the phones. He could have even heard that sirens around 4am, saw that they were at the house he just received the phones from earlier and disposed of the phones and laid low after that.
Idk. . .but all possible. It makes more sense to me than a petty thief stealing a baby and walking around in the area for 4 hrs while making calls from a phone that he knows is tied to a kidnapping.
All MOO.
