When the story of Natasha Kampusch broke in 2006 it seemed like a bizarre one-off. Since then we've heard about Jaycee Dugard and one or two others. Now three more missing women (possibly more) have been found at a place in Ohio seemingly having been held captive for many years. Good conclusion to a tragic story and makes you wonder if there's anyone in the UK, written off as missing, but being similarly held against their will. Thinking about the case of Claudia Lawrence, for example.
