Brooke Skylar Richardson pleads not guilty to aggravated murder in death of her newborn

The 18-year-old woman charged with aggravated murder in the death of her infant pleaded not guilty Monday in a Warren County court. Brooke "Skylar" Richardson is accused of killing, burning and burying her newborn baby in her backyard. Warren County Prosecutor David Fornshell said Richardson "purposely caused the death of the child." The prosecutor said authorities may never be able to say the exact medical cause of the baby's death because of the burning and decomposition that occurred between the time they believe the child was born on May 6 or 7 and when the child was found July 14.
