An 'armed and dangerous' Oxford University bursar who is on the run for murder in the US said he had a passion for torture and bondage on an online dating profile.
Briton Andy Warren is accused of stabbing to death 26-year-old hairstylist Trenton H. James Cornell-Duranleau with Northwestern University academic Wyndham Lathem, 42, before fleeing the Illinois city together in a grey 2017 Hyundai sedan.
The 56-year-old was registered on gay dating app Grindr under the names 'Anything Goes' and 'No Limits', reports the Sun.

Screenshots of Warren's profile, seen by the newspaper, show he claimed to have 'no limits' and wanted to find someone dominant on the gay dating app.
Warren is now on the run in America with Black Death expert Lathem after allegedly murdering the hair stylist in a luxury Chicago apartment.
Yesterday, MailOnline revealed that he vanished a week ago from his home near Swindon without telling his boyfriend.
Police in America and Britain are today trying to piece together how Warren and his alleged accomplice Lathem knew each other and whether they struck up a relationship online before meeting up in Chicago.
Warren was reported missing to UK police on July 25 - two days before the murder - after he disappeared from the council house he shares with his sister Tracey, 39.

Miss Warren and her brother's heartbroken boyfriend Martin Grant, 44, who has been a relationship with the murder suspect since at least 2011, have been desperately looking for him ever since.
A family friend told MailOnline: 'The last thing I knew about Andy was that he had disappeared. Tracey asked if had I seen him and his boyfriend came round the other night and said the same'.
Warren's sister and boyfriend were initially told by police he might be in Spain but he has now turned up in America - a place he had never visited before - where he is now wanted for first-degree murder.

Martin Grant refused to comment on Warren's disappearance today at his home a few miles from his boyfriend's.
US police have launched a nationwide manhunt and a judge has issued first-degree murder arrest warrants for the men accused of repeatedly stabbing Mr Cornell-Duranleau in Lathem's luxury apartment on July 27.
Warren, a former bus driver and train buff who works in payroll at Oxford's Somerville College, is believed to have been days into his first trip to America when the murder took place.
Lathem is an associate professor of microbiology at Chicago's prestigious Northwestern University, where he is an expert in immunising against bubonic plague - better known as 'Black Death'.

Chicago Police spokesman Anthony Guglielmi said last night that they believe the men have fled Illinois, adding: 'The search for them will only intensify. They should do the right thing and turn themselves in to any police station. It's only a matter of time.'
A spokesman for Oxford University and Somerville College also said: 'We have been in contact with the police in the UK and are ready to help the US investigating authorities in any way they need.
'Andrew Warren's colleagues at Somerville College have now all been informed and are shocked to learn of the case.
'Whatever the circumstances, we would urge him to contact the US authorities as soon as possible, in the best interests of everyone concerned.'
Mr Cornell-Duranleau was stabbed to death inside a 10th-floor apartment in the Grand Plaza Apartments complex on North State Street in Chicago.
Thames Valley Police have confirmed the British fugitive was reported as a missing person on the day after he secretly flew out to America.
A spokesman said: 'Andrew Warren was reported missing to the Force on July 25 and officers have been working to attempt to locate him.
'It has been established Mr Warren left the United Kingdom on July 24 and enquiries are in progress to locate him'.
On July 29, Tracey posted a picture of herself with Andy and their dad on Facebook.
She wrote: 'miss dad and wake up bruv life is too precious to waste.'
MailOnline understands his father Derek, 85, died suddenly in September last year.
Family friends, who asked not to be named, said Andy Warren was a 'gentle lad' who would help out his neighbours.
He lived in the house where he had grown up, with younger sister Tracey, and his father, until his death earlier this year.
It came as a shock to the family when Dereck Warren died after his car ploughed into a tree in the village, Longcot, Oxon.
But family friends insisted he was gentle and not capable of murder.
The elderly woman said: 'Andrews a lovely lady. He's always been gay. I can't imagine him committing murder. he's not the type.
'He's a quiet lad. He helps his neighbours.'
Andy had a 'strict' upbringing and would accompany his mum Mabel to bingo rather than playing with village children.
He attended a boy's grammar school after passing the 11-plus.
A man in his 70s added: 'We went out a few days ago and saw a police car parked outside. I heard someone saying Andy was miss missing, and might be in America. I hope he's alright and not in trouble for something he didn't do.'
