The mother of a 5-month-old child hospitalized with a severe head injury told police she thought the blood building behind her son’s eyes came from crying, police said.

Hanahan police on Thursday charged Rachael Felicia Enciso, 30, and her boyfriend Derek Allan Stilson, 23, both of Murray Drive, with unlawful conduct toward a child. A judge on Friday set bail at $20,000 for each parent.

Police reports detail several injuries on the child that went unreported for months, including a hand-shaped bruise.

Stilson told police he roughly played with the child because he was a boy. He told a female detective that she would likely have handled the child more carefully because she is a woman, reports state.

Stilson later admitted to slamming the child on the floor out of anger because he wouldn’t stop crying, police said. The act caused the child to be hospitalized in critical condition with a fractured skull.

The injury caused blood to build behind the child’s retinas, police said. Enciso told police she thought the child had only burst a blood vessel in his eye from crying, reports state.

Stilson was charged with infliction of great bodily injury to a child and held at the Berkeley County jail pending a $250,000 bail.

Doctors discovered the child also had a fractured leg, which had already started to heal. Enciso noticed that the child would not put weight on the leg, police said, but she did not seek medical care for that injury.
