A 25-year-old Onawa woman has been charged with murdering her 15-month-old son by drowning him.
Police say Ashley Cameron was arrested Wednesday afternoon. Officers had been sent to an Onawa home on February 11 because of a report that a toddler wasn't breathing.
He later was identified as Markis Dahms, Cameron's infant son. An autopsy by the Iowa State Medical Examiner's office determined that the boy had been drowned by someone.
Cameron remains in Monona County Jail on $1 million bond. Police haven't released other details about the case.
