A Johns Island woman is accused of choking her son and hitting him with a belt and a coat hanger because she wasn't pleased with his school performance, authorities said.

Hilda Marisol Lanza Ramirez, 32, of Langston Drive was arrested Tuesday and charged with ill treatment of a child, according to Charleston County jail records.

On Nov. 26, a Charleston police officer was notified by a social worker at Angel Oak Elementary School about a possible assault on a student. She handed over a note the student wrote that, in part, said: "The things that bothers me is everybody hits me. My mom thinks I am stupid and dumb," according to a police report.

The boy told the social worker his mother struck him on the back with a belt and hit him on the leg with a coat hanger for doing poorly in school, a police report stated. The boy said his mother also choked him later the same night after growing angry again, police said.

When asked how long his mother had been hitting him, the boy said "a long time," a police report stated.

Officers found a 3-inch bruise on the boy's left in the shape of a coat hanger hook, police said. When the boy pulled down his turtle neck top, officers spotted red bruises on his neck as well, a report stated.

The boy told investigators his mother had forced him to wear a turtle neck sweater to conceal the bruises, and police noted that cosmetics has been applied to the area as well to cover up the injuries, a report stated.

State Department of Social Service workers were called in, and the boy and two siblings were placed with another family member, police said.
