SAN ANTONIO -- Rogelio Archuleta, 26, was arrested Wednesday on three charges of causing serious bodily injury to three adopted children.
"He claims that he didn't know what was going on or why he was being charged," said Lou Antu, a spokesman with the Bexar County Sheriff's Office.
Officials say the three children, an 8-year-old boy and two 10-year-old fraternal twins, were adopted by 40-year-old Iliana Archuleta.
Rogelio Archuleta was arrested Wednesday at the Honey Tree Preschool and Child Development Center, which is owned by Iliana Archuleta.
Authorities said Iliana Archuelta is in Houston with her attorney, and that there is a child abuse warrant out for her arrest.
According to an arrest warrant affidavit, one of the children told investigators the two relatives beat and starved all three of them, and that they were forced to bite each other.
A Child Protective Services official said Iliana Archuleta and her husband adopted the three children back in February of 2011. Archuleta's husband has not been charged in the case.
The Honeytree Preschool and Child Development Center has shut down pending the outcome of the investigation.
