Harvey Nichols beauty consultant Clare Bernal and security guard Michael Pech had only been on three dates when he began a sustained campaign of stalking against her. Eventually, she reported his behaviour to the police - he had been following her, texting her up to 50 times a day, threatening her - and he was arrested. On September 15th, 2005, Pech was out on bail awaiting sentencing for harassment when he walked into Harvey Nichols and shot the 22-year-old once in the back of the head then three times in the face. She died instantly and he then turned the gun on himself.

Nimpha Ong and Ahmed Al-Haddad were tenants of 92-year-old Bridget 'Bridie' Skehan, a wealthy former socialite, at her Bayswater flat when they brutally beat her to death in a gratuitously savage attack in December 2002, in a bid to get their hands on her fortune. Her body was found in a shed to the rear of the building a few days later, having been bundled into a cardboard box and concealed. When the pair were arrested, they blamed each other for the crime but were both eventually convicted of murdering Bridie and given life sentences.

Thomas Hughes murdered pregnant, 22-year-old Krystal Hart with two gunshots to the head on the doorstep of her home in a ruthless execution style murder. Following a long-running dispute between Hart and 'neighbour from hell' Angie Brewer, Hughes took it upon himself to carry out the revenge attack after becoming besotted with Brewer. In a surprising twist, there were CCTV cameras placed above the door to discourage and monitor the feud which Thomas Hughes either ignored or knew nothing of which would help to secure a conviction during the trial. But first, the police had to track Hughes down.

In June 1999, Maureen Hale vanished without a trace, leaving her husband and children behind. Police had long suspected her millionaire husband Martin of killing her after she had demanded a divorce and with damning evidence against him, he was arrested and charged with her murder. That damning evidence? He had offered a friend a large sum of money to hire an incinerator and detectives found a note in his briefcase listing ways to dispose of a body. Martin Hale was found not guilty following the trial and Maureen's whereabouts has never been discovered.
