I love you Dr. G!

Today in the trial of State of Florida Vs. Casey Anthony, there was, as Nancy Grace loves to blurb, a "bombshell tonight".
Who'da thought this case would turn on its heels in just one day of testimony from just one witness.
Before today, the prosecution was plugging along, doing its job, and fairly well.  The defense was getting in some digs, and casting a small amount of doubt, perhaps, but clearly the prosecution had plenty of ammunition.  But, the prosecution still had NO SMOKING GUN.

Enter Dr Jan C. Garavaglia, M.D, aka "Dr. G".  For those unfamiliar, the fine doctor has a show on Discovery Health channel, that focuses on her diagnosing cause of death for bodies that come into the morgue in Orange County, Florida.
She also just happens to be the chief Coroner for Orange County, and was responsible for diagnosing the cause of death of little Caylee Anthony, Casey's now deceased daughter.
When she was on the stand today, a simple question turned into a huge breakthrough for the prosecution, and it came when the defense was asking the questions!
Chaney Mason was trying to ask Dr. G. whether she thought Caylee's death could be ruled an accident.  Her response?  "NO".  Why?  Chaney wanted to know.  Because, as Dr G. went on to say, no one who accidentally killed their child would wait any time at all (let alone 31 days) to admit the accident happened, no accident would involve hiding the body, and no accident would involve duct tape being placed anywhere on the face of a baby.
When Chaney pressed on, asking "Are you 100 percent sure?" "Yes, I'm 100% sure" - you go Dr. G!  This is the slam dunk the prosecution needed, the "aha" moment so often spoken about in terms of whether it could be proven that Casey Anthony was involved with this poor girl's death.

Taking all that has preceded this testimony and adding this revelation that clearly the defense was unprepared to hear, and you have one helluva case.
