Joe Leogue takes a look-back at the week since Karen’s disappearance

“Karen was our only daughter, cherished by our family and loved by her friends. She was an outgoing girl, who travelled the world where she met lots of people and thoroughly enjoyed her life. We will miss her terribly.”

“We just want Karen home safely, we are desperate. She is our only daughter, we love her dearly.”
