Columbus, Ohio, police Officer
Jonathan Thomas was investigating a hit-and-run in Whitehall on Friday when a woman came up to him asking for help, according to
The Columbus Dispatch.
The woman told Thomas that her sister -- later identified as Andrea Ellis -- had cut herself and needed medical attention.
When Thomas arrived at the doorway of the residence, one of the family dogs ran at him, according to Columbus police spokeswoman Denise Alex-Bouzounis. Thomas pulled out his gun and fired, inadvertently hitting the young girl in the leg. The 4-year-old, who is reportedly Ellis' daughter, is in stable condition and expected to make a full recovery.
