A Michigan judge ruled Monday, a 15-year-old African American student who was sent to prison after failing to complete her schoolwork and for reportedly fighting with her mother should not be released and that she was benefiting from the treatment she was receiving in detention.

The girl, who is known simply as Grace, has been detained since May.

Students have rallied behind Grace and say she was disproportionately punished because she is Black.

Grace told the court Monday, “I miss my mom.”
