The Telegraph newspaper in Macon reports that Houston County sheriff’s Lt. Jon Holland said Friday that an autopsy conducted by a GBI medical examiner in Atlanta ruled the cause of death as multiple gunshot wounds and the manner of death as a homicide. The body has been released to the family, he said.
The two girls were alone at their Addington Drive home between 5 and 7 p.m. Tuesday when Carmen Collins used her parents’ .40-caliber handgun to shoot her younger sister in the foyer/living room area, Holland said.
Gasoline was taken from a storage shed, where it was kept to power the lawn mower, and used to start a fire, he said. The gun had been stored safely, he said.
Carmen Collins fled in the family’s 2011 Acura TL, taking with her the gun and a white poodle named Cooper, the family’s dog, Holland said.
She was arrested at about 2 a.m. Thursday during a traffic stop in Columbus, Ga.
