Trinity Carr could face several years in prison for the murder of fellow high school student Amy Joyner-Francis (pictured above).

On Monday, prosecutors charged Carr with criminally negligent homicide. Due to the severity of the crime, the Delaware Department of Justice will seek to have the 16-year-old tried as an adult.

Zion Snow and Chakeira Wright, who were also allegedly involved in their classmate’s demise, will be tried as juveniles on criminal conspiracy charges.

Prosecutors indicated that Snow and Wright did not physically touch Joyner-Francis, but were instrumental in orchestrating the attack that took place in a bathroom at Howard High School of Technology in Wilmington, Delaware, on the morning of April 21 just as classes were beginning.

The honor roll student, who was also 16 at the time, died 90 minutes after the attack and being airlifted to A.I. DuPont Children’s Hospital in critical condition.

“Amy died from a cardiac incident that she was vulnerable to because of a pre-existing heart condition,” the justice department stated at the time. “But the cardiac incident would not have occurred if she had not been assaulted.”

While Snow and Wright could face up to one year in custody if convicted, Carr faces up to eight.
