 Crimewatch reconstruction of the Aylesbury Spade Murder. On 12 March 2007, Mustapha Charkaui and his wife Krystyna were at home in Aylesbury, Bucks, when two men, both wearing balaclavas, jumped over their garden fence, picked up a spade, and smashed the patio door to gain entry into the couple s home. Krystyna ran upstairs and one of the men followed her and struck her in the face with the spade. He then hit Mustapha (also known as Chris) on the back of his head with the spade. Mustapha suffered a fractured skull and went into a coma. He died in hospital 11 days later.
