Police have identified a young boy found dead in a box in the US state of Philadelphia more than 60 years ago.
The child, known to generations as the "Boy in the box", has been identified as Joseph Augustus Zarelli.
Police say DNA technology and detective work helped them finally name the youngster in the case that remains the state's oldest unsolved murder.
The mystery had "haunted this community", said Philadelphia Police Commissioner Danielle Outlaw.
At a press conference on Wednesday, police said they would not release the name of the boy's parents and declined to say who was responsible for his death.
The case remains an active investigation, the police said, calling on the public for help filling in the details of the boy's life.
