A 16-year-old high school student — described as responsible and quiet by her friends — has died in a violent attack in a girls’ restroom at the Howard High School of Technology in Wilmington, Delaware.

“She didn’t believe in fighting,” said a friend of hers, as USA Today reported. “The craziest thing is she died in a fight.”

At a Thursday night vigil for the deceased teen, Amy Inita Joyner-Francis, “community leaders spoke about the need for teens to develop a strong sense of self-worth to stem violence that occurs, often in troubled neighborhoods around Howard High,” said the USA Today report.

No weapons were involved, and the girl reportedly was involved in a fight involving two other students, a spokesperson said.

“All these other girls started banking her — like, jumping her — and she hit her head on the sink,” said another student who was in the restroom at the time, according to Philadelphia TV station WPVI.
