A woman is in custody after three teenagers were shot, one fatally, in eastern Oklahoma, authorities say.
The shooting was reported on Thursday morning at a home about 35 miles south-west of Tulsa.
Okmulgee County Sheriff Eddy Rice says an 18-year-old man was killed and two teenage girls were wounded, one critically.
Mr Rice said a 39-year-old woman, believed to be the mother, is in custody.
Beggs High School Superintendent Brian Terry told reporters that all three victims were students at the school.
