Sheriff's deputies in Florida say a 7-year-old boy is in critical condition after his grandmother mistook him for an intruder and shot him.
Tyler Maddox was taken to a hospital after the shooting, which happened about 1 a.m. Tuesday in Tampa. His condition was not released.
Hillsborough County sheriff's officials say 63-year-old Linda Maddox and her twin grandsons were sleeping after their father had left for work.
She told deputies she had placed a chair under the door knob and when she heard the chair sliding against the floor, she fired a shot in the dark, hitting Tyler.
