CHILLICOTHE, Ohio (AP) --Authorities say a woman was killed in an accidental shooting by a law-enforcement officer during a drug raid in Ross County.

A prosecutor says Krystal Barrows, 35, was accidentally shot in the head Wednesday night after officers entered a home to conduct the raid.

Prosecutor Matt Schmidt says it's not clear whether the gunfire was the result of a weapon malfunction or user error. The Ross County Sheriff's Office refused to annswer questions about the shooting.

A sheriff's office news release said six people were charged during the raid and "large amounts" of heroin were found, along with cash and guns.

The Ohio Bureau of Criminal Investigation is investigating.
