DELAWARE —- A Delaware judge convicted a 17-year-old girl of homicide Thursday for last year’s high school bathroom fight that left another teenage girl dead.

The judge also convicted a second girl of conspiracy in the 16-year-old’s death, but acquitted a third teen of the same charge.

All three defendants, who were 16 when the fight happened in April of 2016, were tried as juveniles.

An autopsy found that Amy Joyner-Francis died of sudden cardiac death, aggravated by stress from the fight at Howard High School of Technology in Wilmington.

Family Court Judge Robert Coonin delivered the ruling Thursday following a week of testimony in the nonjury trial. All three girls charged in the case chose not to testify.

Coonin ruled last year that the girl charged with homicide would be tried as a juvenile. She would have faced up to eight years in prison if she was tried as an adult.

Being declared delinquent, she would be subject to supervision until age 19.
