A Ladson mother suspected of smothering her 17-month-old child was arrested today.

Lorena Contreras-Castillo, 21 of 3872 Fairview Drive, is charged with homicide by child abuse in connection with the child’s Aug. 13 death. U.S. marshals took her into custody this morning, Charleston County Sheriff’s Maj. Jim Brady said.

According to the affidavit from the sheriff’s office, Contreras-Castillo took the child to Medical University Hospital Aug. 5 saying the baby had passed out. Nurses reported that the baby was active and playful, but the child was admitted for observation.

The child was discharged Aug. 8. Paramedics were dispatched to Contreras-Castillo’s home less than six hours later and found the child unresponsive and not breathing.

The child was taken to Trident Hospital for treatment and died Aug. 13 at Medical University Hospital.

Medical officials determined that the child’s oxygen was cut off, possibly by smothering, according to the affidavit.

Contreras-Castillo, who speaks only Spanish, had a bond hearing today through an interpreter. A magistrate can’t set bond on a homicide charge. Contreras-Castillo remains in the Charleston County jail.
