Karen Price was just 15 when she vanished in 1981 and, had it not been for a chance discovery by two builders, her body might never have been found. Because no-one was looking for her.
Dubbed "Little Miss Nobody", Karen had not been seen for eight years when her skeletal remains, wrapped in a carpet, were uncovered by two unsuspecting builders in Cardiff city centre on 7 December 1989.
Her body, found in a shallow grave outside a basement flat on Fitzhamon Embankment, was so badly decomposed it was "impossible" to establish the cause of her death.
Now, more than 40 years on and after the release of her killer, a new documentary has examined how police put together the jigsaw to solve the killing of a teenager "known to no-one" and how it involved "groundbreaking" methods to bring two men to justice.
"It's incredible to think that a girl of that age, 15, can go missing and nobody notice, nobody care," said Tom Bedford, a crime reporter who was working during the investigation.
