GG, I think there's truth in those blogs. I remember reading some of them very early on in the case. If Mark as Tara's husband was Lee's 'rival', then Casey becoming pregnant by Mark would be seen as a betrayal by Lee. It sounds as if Lee was totally in love with Tara, then she supposedly aborted his baby? Thus, the emotionality of his testimony, with all those feelings coming back to him. Maybe he kind of 'rejected' Caylee if Mark was her father. This all makes more and more sense to me. In deference to Lee, then, the family just pretended Caylee's bio dad wasn't important.
Am I remembering correctly that Mark is now deceased? I even remember a jail conversation between CA and ICA where ICA refers to Caylee's 'half-brother'. Any else remember any of this?
I always wondered why the Anthony's didn't go after child support for Caylee. It was some other guy, not Mark, who died. I know there is a huge monster thread devoted to who might be Caylee's real dad, but if you look at a picture of Mark Hawkins, Caylee didn't look at all like him.
She looks more like this guy, JP Chatt, a roomate of one of her ex-boyfriends-- compare the arch of the eyebrow, shape of the nose and mouth:
