A schoolgirl prank gone gruesomely wrong left an 11-year-old Bronx girl hospitalized with severe facial burns — and her rage-filled mom bent on revenge. Relatives of hospitalized Jamoneisha Merritt called Thursday for arrests in the scalding of the girl at her friend’s Bronx apartment. The victim’s mother Ebony Merritt appeared outside the home of Shernett Panton and her 12-year-old daughter Aniya Grant Stuart, spewing obscenities and threats. “I’m going to cut your face, you f---ing b---h!” Merritt screamed at Panton. “I’m going to burn your f---ing house down! You let this happen to my daughter!”
