A 42-year-old nurse, Jessica Vlasac, is charged in connection with the death of her three-month-old son, police say. The allegations center on an incident in which she is accused of punching the infant in the head, and investigators say she later told authorities, “I think I killed our son.” Vlasac was arrested last Thursday and has not entered a plea.

The Daily Mail reports that the charge is felony aggravated child abuse resulting in the death of a child. The coverage also includes details that investigators say she was wearing a diamond ring during the alleged assault. Neither outlet indicates a trial date or provides statements from the defendant or her attorney in the available reports.
