Misty is the key to Haleigh's disappearance
I am a retired Psychologist who worked thirty years with many, many personality types, and I am also an em-path.
Misty holds the answers to where Haleigh is. Her personality relates to a narcissistic personality disorder. This means that she is highly manipulative, self-centered, cold, and quite capable of hurting this child and thinking nothing of it. She seems to be jealous of Haleigh's relationship with her father, and does not want to share him with her. Haleigh is just an annoyance in her life and she wrestles with what to do with her.
On the day she went Missing Misty was agitated from a three day drug binge, was resentful of having to babysit, and when her brother, Tommy, was over around dinner time that evening shared with him how she did not want Haleigh around any longer, and actually never liked her.
Misty's entire family doted on her, made her believe she could get anything she wanted; therefore, Tommy wanted to please his sister, and Misty offered Tommy some drugs if he would get rid of her. I do believe that Joe may be involved as well, but I am not picking up on what level. He may have been invited into to this entirely by Tommy, but he knows what has happened to Haleigh. All three of these people know what happened to Haleigh; yet, Misty is the ring-leader in this very dark, sinister act.
I do sense that this case will be solved, and we will soon find out the real story. Her body is around or in water, and she died the night she went missing.
