Gareth Williams, a maths prodigy, worked for GCHQ, the UK’s Government Communications Headquarters as a code-breaker.
On Monday, August 23, 2010, his colleagues grew concerned when he failed to come into work for several days.. When the police entered the flat, for a welfare check, they were confronted with Gareth's naked body in the bathtub stuffed inside a bright red North Face sports bag, which was locked from the outside.
