The second day of testimony in the trial of Joshua George, accused of violently shaking his infant son and delivering him to his grandparents for baby sitting has concluded. Morning testimony was a continuation of cross examination of the infant’s grandmother Cheska Rotellini, supplemented by video of her interviews with police. Defense attorneys tried to show Rotellini’s qualities as a baby sitter as deficient and unqualified to care for a child. They pointed to several instances of bruising and a battered lip on the infant that was in her care in the month leading up to his death. Afternoon testimony featured expert witness testimony from independent forensic pathologist Dr. Jennifer Hammers. She described her report provided to prosecutors on the cause and manner of death of the infant. She classified the cause of death as blunt force trauma to the head. The manner was homicide. Defense attorneys concentrated on timelines of when someone several months old could develop bruising and brain swelling associated with a skull fracture. Hammers testimony said that especially in the case of infants, those symptoms can be immediate or delayed by several hours. She did say the force needed to fracture the infant’s skull would have needed to be significant.
