Police are investigating a shooting involving a child and his grandmother.
A 7-year-old boy is in critical condition after his grandmother mistook him for an intruder and shot him.
Sixty-three-year-old Linda Maddox told Tampa, Florida, sheriff's deputies that she had placed a chair against her bedroom door handle for extra protection early yesterday morning.
When she heard the chair sliding against the floor, she assumed it was someone breaking in and she grabbed a loaded .22-caliber revolver.
Instead, she shot one of her twin grandsons.
