(KMIZ)Prosecutors and the defense laid out their arguments during the second day of a Boone County baby death trial on Wednesday. Brown is charged with first-degree involuntary manslaughter in connection with the death of Ayla Gibson. Buchanan told jurors Gibson was a happy and healthy baby, and that they should expect to hear from doctors and witnesses that can testify to that. "She failed her duty that she owed to Ayla Gibson and because of that, Ayla Gibson suffocated." He told jurors that while what happened was a tragedy, that does not mean that a crime was committed.
