DES MOINES, Iowa (AP) — A Des Moines woman has been charged with child endangerment over the death of her 2-year-old brother.

Polk County Jail records say 18-year-old Denver Emery remained in custody Tuesday. Court records don't list the name of an attorney who could comment for her.

The court records show Emery and her boyfriend, 37-year-old Nicholas Rivera, took the little boy to a hospital in May. Doctors said the boy's injuries were consistent with "abusive brain trauma" that wasn't accidental, and they noted bruising on the boy's back that may have been caused by fingers. Rivera faces the same charge and is due in court next week.

Police say Emery and Rivera were the boy's sole caregivers in the two weeks leading up to his death May 24.
