It took a Warren County jury less than a day to find 24 year old Brandon Warrington guilty of second degree murder in the death last November of 5 year old Gary Carpenter. Jurors believed prosecutors and Warren County D.A. Kate Hogan who said that Warrington inflicted the injuries that led to the boy's death from severe head injuries. The Boy's mother, Jennie Mattison, plead guilty to hindering prosecution by lying to police.. that is a felony. A judge dropped a more serious charge of Endangering the welfare of a child, against Mattison, saying that there was not enough evidence. Warrington, who was also found guilty of manslaughter and endangering the welfare of a child, will be sentenced on July 11th... He faces at least 15 years in state prison, maximum sentence could be 25 years to life.
