WILMINGTON, Del., May 10 (UPI) -- Three teenage girls have been charged in Delaware for the death of 16-year-old Howard High School of Technology student Amy Inita Joyner-Francis.
Officials said they are working to have one of the three girls, who was charged with criminally negligent homicide, tried as an adult for punching Amy in the chest and head. The suspect faces up to eight years in prison.
The two other girls are facing up to one year in prison after being charged with third-degree criminal conspiracy. Authorities determined the three girls planned a confrontation with Amy in the girls' bathroom on April 21, but only one of the girls physically struck Amy. The fight was filmed.
Court documents detail that communication between the three girls showed they planned the fight about 20 hours before the assault. An autopsy determined Amy's death was caused by "sudden cardiac death due to large atrial septal defect with a contributing factor of physical and emotional stress due to physical assault."
"In layman's terms, the medical examiner determined that Amy died from a cardiac incident that she was vulnerable to because of a pre-existing heart condition, but the cardiac incident would not have occurred if she had not been assaulted," a Medical Examiner's Office spokesperson said.
