The daughters of a former Norfolk woman beheaded in Tenerife have met the killer's family in North Wales to discover more about him in their quest for an independent review into how he remained free to murder.
In February homeless Bulgarian drug addict Deyan Deyanov, 29, was sentenced to 20 years in a secure psychiatric unit on the holiday island after slaying former road safety officer Jennifer Mills-Westley, 60.
Deyanov - who had been sectioned in North Wales in 2010 under the Mental Health Act - attacked the victim while she was shopping in the popular resort of Los Cristianos in the Canary Islands, on May 13 2011.
Deyanov, a delusional drifter living rough in a derelict building on Tenerife's Los Cristianos beach, used crack cocaine and LSD and built a shrine full of religious imagery.
His history of violence can be traced back to his hometown of Ruse, a city in northern Bulgaria known as the Little Vienna.
After leaving Bulgaria, he drifted all over Europe, staying in Edinburgh, North Wales and Ibiza, before arriving in Tenerife.
Released from North Wales care in October 2010 he travelled to Tenerife.
He believed he was Jesus Christ and heard voices commanding him to kill.
Well-known as a troublemaker he had been arrested on the island at least four times between January and May 2011.
In January 2011 he committed a series of random violent attacks and was committed to La Candelaria hospital's psychiatric unit, but was released on bail in early February.
Days before he killed Mrs Mills-Westley an arrest warrant was issed for him.
After his conviction, the victim's two daughters Samantha Mills-Westley, 39, and Sarah Mills-Westley, 43, hit out at the authorities for their handling of Deyanov.
Tonight, in a Channel 4 Dispatches programme, the sisters, who are calling for an independent review, meet the killer's aunt in North Wales to ask if he received the right care.
The programmes airs at 8pm.
