British banker Rurik Jutting was today found guilty of the sadistic murder of two prostitutes at his Hong Kong flat.
The 31-year-old faces a mandatory life sentence after being convicted at a trial that featured horrific video evidence of rape and torture.
Jurors had watched as one of the women begged for her life as she was forced to lick a toilet bowl before Jutting savagely slit her throat.
He also made a video showing off his 'torture kit' that included a blowtorch and sex toy wrapped in sandpaper, which he intended to use on his next victim.
The depraved banker had chillingly described how he would go hunting for his next "prey" after killing his first victim, Sumarti Ningsih, and stuffing her mutilated body in a suitcase on the balcony of his luxury flat in Hong Kong's red light district.
The family of his second victim, Seneng Mujiasih, today said they want to see him executed.
In a letter read out to the court by defence counsel Tim Owen after the verdicts, Jutting said he was "sorry beyond words" and that he was "haunted" by his actions that "were horrific even by the standard of homicide trials".
"The evil that I've inflicted cannot be remedied by me," the letter said, adding that he was "aware of the acute pain I've caused to their loved ones".
Jutting, a £350,000 a year trader with Bank of America Merrill Lynch, had claimed he was out of his mind on drugs and drink when he carried out the double murders in October 2014.
Two top British psychiatrists flew from the UK to give evidence and said Jutting was also suffering from narcissistic personality disorder and sexual sadism disorder.
A combination of the orders they told the court meant he was not in control of his actions.
The Cambridge University educated banker had pleaded guilty to manslaughter on the grounds of diminished responsibility.
But prosecutors refused to accept the guilty plea and insisted he be tried for murder.
After listening to and watching some of the most distressing evidence ever heard in a Hong Kong courtroom the jury rejected the manslaughter plea.
They found Jutting was a sexual sadist who took pleasure in inflicting pain on women.
The deaths of 23-year-old Sumarti Ningsih and 26-year-old Seneng Mujiasih were the result of Jutting acting out his depraved sexual fantasies after years of watching violent porn.
The banker's parents and younger brother from Surrey were not in court to see him convicted and had not attended any of the trial.
Jutting had showed almost no emotion as he sat behind a glass-fronted dock in courtroom 36 at Hong Kong's High court during the trial lasting two weeks.
He was almost unrecognisable from the bloated and unshaven man who photographed after his arrest two years ago.
The jury of five men and four women were told how the high flying banker's life spiraled out of control due to his addiction to cocaine, violent porn and prostitutes.
They had been warned some of the evidence, including 43 videos made by Jutting on his iPhone, would be shocking and disturbing.
Those videos would form part of a self-confession by the bloated banker as he delivered several rambling monologues.
Several of female jurors could barely watch the films where a naked Jutting showed the body of his first victim lying on the floor with her throat cut.
In one 20-minute video Jutting could be heard saying: "How much do you love me. If you say yes, I will hit you once. If you say no I will hit you twice. If you scream, I will punch you."
In another he says to the camera: "It's Monday night, I've held her captive since early Saturday. I've raped her repeatedly, tortured her, tortured her badly."
Jutting was no stranger to Ningsih having met her two weeks previously at a hotel near his home.
He had rough sex with the prostitute who told friends she had not enjoyed the experience.
When Jutting called her again she agreed to meet at his flat setting in motion his plan of torture and rape.
First he tied her up and shaved her eyebrows in an attempt he said to "dehumanize her".
He whipped her with a belt and used pliers on her nipples with the violence, fueled by cocaine, escalating all the time.
Ningsih, who was known to friends as Alice, was made to eat faeces from a toilet bowl and repeatedly raped.
All the time Jutting threatened he would kill her if she did not cooperate and at other times told her he loved her.
Shortly before her death Jutting made her lick out a toilet bowl and remarked that she did it with a smile on her face.
After three days of humiliation, pain and degradation he cut her throat.
"Three days of torture, rape and mentally brutalised," he said of her time with him in one of his videos seized by police and used in the prosecution case.
"She was my property and there to please me," Jutting spoke into his iPhone camera in one of his first videos after the killing. "Frankly, I am addicted."
Ningsih's body was wrapped in plastic and stuffed into a suitcase to be left on the balcony.
The court heard Jutting had been snorting up to 20g of cocaine a day - enough to put an ordinary person in a coma.
The drug was said to have given him 'Dutch courage' to carry out his darkest sexual fantasies, which had been building up after years of watching violent pornography.
Depraved murderer and arrogant private schoolboy
Depraved Rurik Jutting was already suffering from a personality disorder at the age of 11 when he won a place at a top private school.
The killer banker told a psychiatrist he was 'offended' when his mum Helen rushed to congratulate him on winning a scholarship to the elite Winchester College.
Jutting said he felt angry that his mum would even consider he would not win a place at the £34,000-a-year school.
Such arrogance would follow him through his teen years and into his career as a banker where he believed he was better than others.
He would later say he was sexually abused at the school when he was forced to give oral sex to another student.
Four top psychiatrists - including two from the UK who flew to Hong Kong to give evidence - agreed Jutting had a narcissistic personality disorder.
Coupled with a sexual sadism disorder and hooked on cocaine and alcohol the lethal combination turned him into a killer who wanted to carry out his six sexual fantasies.
Jutting, 31, was completely open talking about his life while being held on remand in prison during the last two years.
He had no choice but to be interviewed as he was seeking to escape a murder charge and be convicted of the lesser charge of manslaughter by reason of diminished responsibility.
The four medical experts all came to conclusion Jutting had a narcissistic personality.
A person with the disorder has an inflated sense of their own importance and a lack of empathy for others.
The confidence they display masks a fragile self esteem with the sufferer vulnerable to any criticism.
Forensic psychiatrist Dr Richard Latham told how Jutting refused to accept he only got a second class honours degree in law from Cambridge University.
Rather than blame himself, Jutting insisted the examiners were too stupid to understand him
The court heard he made sex tape with one girlfriend when he was 17 years old and also enjoyed outdoor sex.
One of his partners asked him to beat her up during sex and tie her up - signaling the start of his enjoyment of rough sex.
Jutting, who was a member of the rowing team at Peterhouse College in Cambridge, had no shortage of female admirers and until his arrest in 2014 had nine significant relationships.
But the court was told he had few male friends and at night would surf porn websites, seeking out increasingly violent images. He subscribed to one website which featured women being tortured.
It was at this point that the sexual sadism disorder began to take control of his life and his sexual fantasies became even darker.
His use of prostitutes began in 2009 when he got his first bonus working for Barclays Bank in London.
Jutting joined in an orgy with a group of men who had sex with three women and was hooked on rough sex. He told doctors he liked to watch men having sex and also liked to be watched.
He claimed to have attended one sex party with a former Premier League footballer, but his name was not mentioned in the court.
Hong Kong based psychologist Dr Kavin Chow Kit-Wan said Jutting told her he found control and submissive sex more arousing and would push the limits with prostitutes.
But he also liked gay sex and searched the app Grindr for black men to have sex with. In Hong Kong, Jutting rented a flat in the red light district where girls, mostly Filipino and Indonesian, sell their bodies to the rich expats earning fortunes in the banking world.
He would also make regular trips to Manila to a seedy area known as Angeles City where he would have sex with numerous girls.
Jutting's intake of cocaine had increased considerably and this fuelled his sexual urges even more. He fantasised about returning to the UK and kidnapping three teen girls to keep as sex slaves while also thinking about snatching a young mum.
