ATLANTA -- The sister of Coretta Scott King says Martin Luther King's widow died at a holistic health center in Rosarito Beach, Mexico. That's about 16 miles south of San Diego.
Edythe Scott Bagley said she got a call about her sister's death early this morning. Coretta Scott King was 78.
A family statement said King died overnight.
Former Atlanta Mayor Andrew Young, who's close to the family, told NBC that King's daughter Bernice went in to wake her up last night but was unable to do so.
Coretta Scott King had suffered a serious stroke and heart attack last year. Flags at the King Center in Atlanta have been lowered to half-staff.
