Missing by Nathan WK 17

It had been 2 months since Ciara O’ Brien disappeared and we were getting nowhere in the investigation until we found, hidden amongst the hedge shrubs where she was last seen, a little penknife with specks of blood on the open blade. We brought it back to the lab and got it analysed so we could identify whose blood was on the knife. When the results came back, it was Ciara’s blood as well as somebody else’s fingerprints on the handle. We now had a murderer¬† and Ciara’s body¬† to find but how could she just disappear when she was seen by loads of people in broad daylight?
