Get out the cork board and red string because the police have an assignment for you. The AFP has created an online "investigative board" that peers into Australian cold case files with vital clues provided by police. There are around 2,500 missing people in Australia and police have evidence of 750 human bodies that remain unidentified. To mark this National Missing Persons Week states and territories nominated eight Jane and John Doe cases for public examination. Forensic specialists approximated how the victims would have looked by estimating their age, ancestral origin, hair and eye colour, face shape and features. Information about clothing and items found at the scene are among the clues made public during the Can you solve this case? campaign. "The community plays a critical role in helping police with information that can help to solve a missing persons case," AFP Assistant Commissioner Hans Koenderink said.
