If I were on the jury, Andrea's phone records would be the first evidence I would look at. I'd make a time line and see just how long she was on the phone with her mother during her ride to the day care. IIRC, she made at least one call during that ride, according to Don Sneiderman. (If I'm wrong, correct me please.)
Also, according to mom, she was hysterical and "comatose" on the ride to the hospital. Yet, she doesn't remember if Andrea used her cell phone. The defense also made a point that she gave Andrea Lippman her cell phone in the hospital. Wonder if that will be made much of?
BTW, this officer is making a real HIT on the defense. On January 4, she mentions nothing about Hemy and the fear she had.
