More than 60 British university students joined Australia’s Murdoch University and police agencies from 14 countries to work on six cold cases involving missing children and child homicides. The four-month effort was part of the third International Cold Case Analysis Project (ICCAP). The students’ findings led detectives to further investigate one of the cases; and last year, the project prompted investigators to exhume the body of “Gentleman John Doe” – helping identify an unknown man buried 30 years ago.
