VIDEO: Karen Buckley: A young woman went out, never to return home

This day last week a young Cork woman was looking forward to a night out, blissfully unaware that she would never come home.
Karen Buckley arrived at Glasgow’s Sanctuary nightclub with a group of friends at approximately 11.45pm last Saturday night. She was captured on CCTV leaving the club with Alexander Pacteau, the 21-year-old director of a courier firm.
