Berlin prosecutors say the suspect in the slaying of a 4-year-old migrant boy from Bosnia has confessed to killing another child.

Prosecutors' spokesman Stefan Stoehr told The Associated Press on Friday that the suspect confessed to killing a 6-year-old boy who went missing from near his parent's home in Potsdam, outside Berlin, in July.

Stoehr had no further information.

The 32-year-old German man was arrested Thursday at his mother's house in Brandenburg, near Berlin. Police say he confessed to killing 4-year-old Mohamed Januzi, who was abducted in October from the capital's central registration center for migrants.

A boy's body was found in the trunk of his car and an autopsy is being conducted.
