GREENSBORO, N.C. -- An 11-year-old girl was shot to death by her teenage brother in their home, police said. The circumstances were still under investigation.

Raanika Denette Seagroves and her brother were apparently downstairs in their apartment when the brother, whom police declined to identify, picked up a .410-gauge shotgun and it went off.

"It may be a week or so before we know for sure if there will be any charges filed," police Capt. Gary Hastings said. "We don't have any evidence of any kind of altercation that we know of so far."

Police said four people were in the apartment at the time of the shooting: the girl, her older brother, her father and another, unidentified person. The father was upstairs at the time.
