Thousands of people are reported missing in Scotland every year, and while most are traced within 48 hours, some remain a mystery years on.
For months, years and decades these people remain lost without a trace, with circumstances surrounding missing persons cases often remaining unclear.
Currently, there are details of 30 missing people on the Police Scotland website.
Here, we take a look at the named and faces of each of those cases in the hope that one day they can be solved.
