[8] Dennehy, born August 1982 in St Albans, Hertfordshire, grew up in nearby Harpenden,[10] and was an absent mother of two young children at the time of the killings.
Lloyd stated Dennehy had wanted to kill nine men in total, seeking to be like Bonnie and Clyde.
[17] The trial began at the Old Bailey in London where Dennehy could be seen laughing during proceedings, stating, "I have pleaded guilty, and that's that" when questioned about her decision.
At one point during her trial, Dennehy stood up and told presiding Mr Justice Spencer "I don't wanna be controlled by anybody.
[18] On 28 February 2014, Mr. Justice Spencer called Dennehy a "cruel, calculating, selfish and manipulative serial killer" [19] and sentenced her to life imprisonment with an additional order that she should never be released due to the premeditation of each murder.
[21] Two men, Richards, 47, and Leslie Layton, 36, stood trial charged with a range of crimes relating to assisting Dennehy.
[30][7][31] After the trial it emerged that the Probation Service was supervising Dennehy at the time of the murders as she had been convicted of assault and owning a dangerous dog.
Government lawyers argued isolation was necessary due to the nature of Dennehy's offences and the risk she could pose to the public if she were to escape.
Mr Justice Singh found solitary confinement was "in accordance with law (...) at all material times it has been necessary and proportionate".
[39] In June 2020 Dennehy was reported to be in a relationship with another prisoner, Emma Aitken, a 25-year-old serving a twelve-year sentence for her part in the murder of a man whose body was dumped outside a social club.
[44] Her former boyfriend and father to her children told his story in an episode of documentary series The Killer in My Family which aired on Discovery owned channel Quest Red in the UK.
