A week ago, 10-year-old Raniya Wright was taken to the hospital, unconscious but breathing, following a fight with another student at her South Carolina elementary school. Two days later, she died.

On Monday, her parents demanded answers.

“I want to find out what happened, how it happened and who was involved,” her father, Jermaine Van Dyke, said at a news conference in front of Forest Hills Elementary School in Walterboro, S.C., about an hour west of Charleston.

A lawyer for Ashley Wright, Raniya’s mother, said the family wanted to know whether there was “appropriate supervision in the classroom, and what, if any, steps did school administrators take to intervene in the fight.”

The lawyer, Margie A. Pizarro, said Ms. Wright “trusted the school to keep Raniya safe from harm. She trusted the school to protect Raniya.”
