Operation Mayan

On the evening of March 18 2001, 22-year-old Sian O’Callaghan enjoyed a night out with friends in the Old Town of Swindon in South West England. The flat she shared with her boyfriend Kevin Reape was less than a kilometre away, making it an easy walk home. 

However, Sian never arrived home, despite CCTV footage confirming she had left the Suju Nightclub at 2:45 AM. A local taxi driver was soon identified as the main suspect, but as police investigated him, what unravelled was truly shocking.
