Authorities have recovered the body of a child from the Baltimore Harbor and say it may belong to a 3-year-old whose father confessed to throwing the boy off the Francis Scott Key Bridge.

The body was taken to the state Medical Examiner's office for identification after it was recovered Saturday morning by fire crews from the Patapsco River.

Police say detectives went to the area as part of their investigation into the death of Turner Jordan Nelson.

The boy's father, 37-year-old Stephen Nelson, has been charged with first-degree murder. According to court documents, Nelson told police he threw his son off the Key Bridge in February, saying demons made him do it.
