Oh, I'm so sorry about your dad.
If you really want a roundup of the day's events so far, it was a whole lot of nothing. The DT witness was a neuropsychologist who said Dr. DeMarte didn't know what she was talking about, Dr. Horn didn't know what he was talking about in regard to the bullet wound and that he isn't getting paid to testify. Then JM made him admit that previous courts had deemed him less than credible, that his institute is getting $250/hour for his testimony and he makes $117,500 a year. Then he laid into him for not being a medical doctor and claiming the ME was wrong. In between, the so-called doctor burped and spilled his water. Twice. Now the handsome medical examiner is back on the stand with the attitude of, "Why the f am I testifying to this same crap that I've told you is fact all over again for the third time?"
Hope that helps. And I hope that things start to turn the corner for you and your family.
