So with a few tweeks the theory of Misty taking the kids out of the bed, taking them to Tyler Street so she can party; using the van to get there with blanket in tow is possible. Then she gets someone to drive them home, say around 2- 2:30 she puts kids in different beds. Jr may have seen the person in black picking up Haleigh from Tyler to put her in the brothers van, or he remembers going to Tyler and someone picking up his Sissy. I don't think that Chelsea took the only van they had, so going home Misty may have used a different car or van. So it is possible that once home she puts the kids down, she drove back to Tyler and walked home to find the door propped open and Haleigh missing. I really don't believe LE wasted time, I think they were lead in the wrong direction. Someone took that van out that night and did the damage, it could be related to her missing. I also think that Misty took the kids out and that explains some of her confusion and JR's comment. I don't know who all was at Tyler that night, but the police were there and that comment blows a hole in Misty's story big time.
