DALLAS - Three children were kept in a hotel bathroom for about a year and were “horribly emaciated’’ when police found them earlier this month, authorities said. One said she had been repeatedly sexually assaulted.

The children were so emaciated that they threw up when child protective workers first tried to feed them. The children’s lips were dry, swollen, and cracked, their ribs were protruding.

The children’s mother, 30-year-old Abneris Santiago, is charged with injury to a child. Her 37-year-old live-in boyfriend, Alfred Santiago, is charged with aggravated sexual assault and continuous sexual abuse.

According to an arrest affidavit, Abneris Santiago called police on July 2 and asked for help getting her children and belongings from the hotel. Officers found a healthy 1-year-old girl - the child of the Santiagos, Jamison said - in a crib.

Inside the bathroom, they found an 11-year-old girl, a 10-year-old boy, and a 5-year-old boy - Abneris Santiago’s children from other relationships, Jamison said. It was apparent they suffered from “serious physical, emotional, and mental neglect,’’ according to the affidavit.
