Demery's daughter, Alicia Versluis, was reported missing May 7, said Pomona police Sgt. Demery told authorities that she had taken the toddler and her twin sister to a park that day, and that Alicia had disappeared while Demery was reading, Crabb said.
Police say the charges stem from the conditions in which the girls lived.
Crabb said the family's home is a storefront, but she did not elaborate on the condition of the building. Authorities said the child abuse charges were added after a physician examined Alicia's sister. No details of her condition were released. Jones was arraigned last week, but Demery's arraignment was postponed to allow her to recover from the birth of a daughter. Crabb said the baby girl was full-term and healthy.
