According to the police report, the girl admitted to poisoning the boy because their mom loved him more than her. She also allegedly told police she did it because he was annoying her.

The girl was arrested on an attempted murder charge. She was taken to the Cumberland Hall facility in Hopkinsville for evaluation.
