If KC doesn't woman-up she's doomed.
Saying that Caylee wasn't on Suburban would be same old/same old. More fibs from KC and trying to blame somebody else. George wouldn't leave Caylee's remains so close to the road. He wouldn't wimpily give up digging after a stroke or two. If he knew about the duct tape, there wouldn't have been duct tape on his gas cans for LE to photograph. Caylee wouldn't have been left in the laundry bag that had previously hung in Caylee's room.

An accident theory, AZlawyer's recommendation, I think might win over a juror or two. The psych experts wouldn't say KC had a split personality or anything like that. They would say, like a battered wife, KC's had become so reasoning-impaired from life in the Anthony house, that she behaved in ways that make her look guilty even though she is innocent.
KC would have to admit to lying and covering up Caylee's death (both givens anyway), but not to murder. The impaired reasoning part would be tough for KC to admit to, but Cindy said when KC gets cornered she usually "tells the truth" (she 'fesses up to smaller misdeeds to get away with the big ones). So KC already knows the drill.
KC's defense lawyers and their experts could say, "KC has spent a lifetime being terrorized by her father's temper, her father and her brother's abuse and the high expectations of her very strong nit-picking mother. A lifetime of abuse and belittling made KC an insecure wreck. She can't work. Whatever KC tried to do was never good enough...so why even try? Desperate to succeed at something KC went from man to man. Compliments from those men made KC feel worthy. In their arms she was good enough. But, all the men and the family dysfunction left KC confused and in turmoil. KC's confusion, her fears of being belittled and her low self-esteem crippled her to the point of being paralyzed,..for years. KC might have been 22 years old the summer of 2008 but inside she was still an immature little girl. Scared. Worthless. Powerless.
KC knew she had to do something but instead frittered her days away lulled by her soothing computer.Hour after hour passed without KC even realizing it. But the activity killed KC's internal pain.
KC forgot to watch Caylee.
"Caylee fell/choked/drowned/had a heart attack.
KC couldn't call anyone to get help after the "accident" because her parents would "know" about her ultimate screw-up. They'd blame her the way they always did. Caylee's death was proof positive that KC was the bad mother Cindy said she was. KC couldn't bear to face her mother's pain. Her shame was overwhelming. Also if KC called for help, her family would find out something else KC was ashamed of. Something besides not watching Caylee. To avoid being belittled KC had invented a "perfect" job. The lie compounded when KC had to make up Zanny so her family wouldn't know she didn't have a perfect job. She had to steal to keep her phone so she could text so she wouldn't feel her internal pain. She also had to lie more and steal more and send herself e-mails so Cindy would believe she had a job which made KC's esteem even lower.
Like a deer in headlights, KC didn't know which way to go. She headed to a "friend". Maybe that "friend" could somehow make her feel worthy...make her forget.
Yes, KC is a liar. But, KC's low self-esteem, her father's rages and her mother's belittling and competitive ways drove her to it.
When Caylee fell/choked/drowned, KC coped the way she'd learned to cope in order keep her sanity. She put on her happy face and lied. It is what she'd always had to do for peace and acceptance.
KC's misguided immaturity (brought on by her dysfunctional upbringing) led KC to try to cover up the accident. Horrifically.
What I believe might resonate the most with jurors is a story that includes some truth and rational reasons for KC's awful behavior.
