The self-confessed ‘monster’ who strangled a history teacher he met online to death and then had sex with her body was jailed for 26 years.
Carl Langdell, 26, murdered history teacher Katie Locke, 23, in a hotel room just two weeks after they first met on internet dating site Plenty of Fish.
After killing her on Christmas Eve last year he used a bar of soap to lubricate her genitals so he could abuse her body.
He then took pictures of her on his iPhone, which he viewed later before deleting.
He then wrapped her body up in bed sheets and a duvet and dragged it outside before dumping it in some bushes.
Yesterday law student Langdell, who admitted murder, was sentenced by judge Andrew Bright at St Albans Crown court.
The judge told him: “I am firmly of the view that you pose a very great danger to women and young girls with whom you come into contact with in the future and I note that you have described yourself to others as a monster and a psychopath because of what you did to Katie Locke.
“Once you have served the minimum term I have set, it will be for others to decide when, if ever, it will be safe for you to be released.
“They will be guided by psychiatric opinion on your condition when that decision has to be made.
“In this regard I note that in his report dated April 20, 2016 by Dr Philip Joseph, who is arguably the country’s most experienced consultant forensic psychiatrist in cases of this kind, expresses the opinion that you suffer from an emotionally unstable and dissocial psychopathic personality disorder with the result that the risk you pose to women is likely to remain significant for the foreseeable future.
“He is pessimistic about whether psychiatric treatment will bring any long term change and I want to make it clear that so am I.”
He added: “Katie was a thoroughly decent and innocent young woman who had done you no harm at all.”
“You lied to her about being a lawyer with you own firm when the reality was that you had recently been made the subject of a suspended sentence of imprisonment of Bristol crown court for making death threats to women which you communicated to a community nurse involved in caring for your mental health.”
Speaking on at the court on Thursday Katie father Bill spoke about the effect her death had had on them.
Fighting back tears Bill said to Langdell: “On the internet (you say) you are an ordinary, decent human being.
“You are very ordinary but you are not a decent person.”
He added: “Katie was born in January 1992 like a new star. The day she was murdered that star was extinguished.”
He added: “Katie’s loss is huge for me. In hindsight I did not tell her enough how pretty she was or how much I loved her.
“Maybe she knew it but now I feel probably at fault for not telling her.”
Law student Langell claimed to police that Katie had told him she enjoyed kinky sex and being choked and died in a sex game gone wrong.
But prosecutor Ann Evans told the court on Thursday that there was no evidence to support his claim.
She said: “Katie was wearing a black dress and Langdell asked her if she liked BDSM (Bondage, Domination and Sado-Masochism).
“He claimed she said that she did and she enjoyed being choked.
“At this point he began to strangle her and decided to kill her.”
Mrs Evans said that Langdell was lying and all of the forensic and circumstantial evidence is that Katie’s had very conservative tastes in sex.
She said: “The tragedy of this case is that is what Katie did, like thousands of other young people, agreed to a date with Carl Langdell.
“She accepted what he told her about himself.
“At the end of their first date in the early hours of the 24 December last year she agreed to go back to a hotel with him.
“He strangled her in that room and dragged her body in a skip outside the hotel.
“Katie’s body was found near the hotel.
“(It was) wrapped tightly in a sheet and covered with a duvet. On top of that duvet sat a metal floor standing ashtray.”
Earlier that evening the couple had been out for drinks in London and called for a taxi to take them to the Theobolds Park Hotel in Waltham Cross in Herts.
The taxi driver who took them remembers both the pair being drunk, especially Langdell.
Katie paid him £65 for the fair but Langdell was violently sick throughout the whole journey.
It got so bad that he pulled over for several minutes on the A10 to allow Langdell to be sick.
He insisted that they pay an additional £80 for the mess which Katie did when they arrived at the hotel.
When the pair arrived at the hotel and about 3.30am on Christmas eve last year Mr French, who was working on reception recalled Langdell stumbling.
He said: “I shouldn’t have had the shots.”
He remembers Katie kept apologising to him.
Katie signed the £115 bill for the room and the pair made their way there, with Katie supporting Langdell.
Around 30 minutes later Katie called reception and asked for toothbrushes and toothpaste which Mr French delivered.
He saw Katie who seemed fine and was fully clothed at this point.
The man in the adjacent room to the pair got up for a cigarette at around 6.25am.
He went out to the fire escape and saw that the door had been jammed open using a coat hanger that was later discovered to have been taken from the pair’s room.
Later that morning Langdell called reception and paid for a late check out.
A cleaner later went into the room and discovered that all the bed sheets had gone missing and a window was broken.
They also noticed that a phone that had been left in the room was ringing, this was Katie’s father Bill trying to ring her.
At noon Langdell came back and dropped the room key off at reception without saying anything.
By this time Katie’s friends were getting worried about her and were trying to find out who she had been out with.
Katie had sent a picture of Langdell and his full name to a friend before she died.
She googled his name and found a website called Carl Langdell Legal Associates which was based in Cheshunt, Herts.
Katie’s father then drove round there to find out what had happened to his daughter, a University of Southampton history graduate.
Meanwhile Katie’s friends were frantically calling her mobile to find out where she was.
Someone eventually answered and with long drawn out breaths whispered Katie’s name.
The called then ended and all calls to Katie’s phone went straight to voicemail after this.
During this time Langdell contacted a woman he had been seeing for a couple of months after meeting on Tinder.
Mrs Evans said: “He told her he had killed someone. He gave no explanation as to why,
“He told her they couldn’t be together any more because he would be in prison for a long time.”
The woman immediately deleted all conversations and his number from her phone.
At 11.56am on of Katie’s friends sent Langdell a message on Facebook asking where she was.
He replied with two question marks and said he wasn’t with her.
Mrs Evans said: “He said he had no idea where she was, she had got a taxi ages ago. He said he had tried to call her but her phone was off and her battery had died.
“He had hours before left her body in the ditch.”
When Katie’s father was passed on Langdell’s family home he got in his car and drove round there.
Langdell’s mother came out of the house and said she had just spoken to her son who told her he had killed a girl.
Mr Locke immediately called the police.
Before the arrived Langdell said to his mother: “I am a monster. I put her in the ground, I wrapped her up in a quilt. I put her in a trolley.”
He said he had had too much to drink and didn’t want to ruin Christmas.
After Langdell was arrested he told officers where Katie’s body was.
He then told officers: “She didn’t even fight. I expected her to hit out or something.”
He was taken to Stevenage police station where he was interviewed and told officers he was narcissistic and lacked empathy.
Toxicology results revealed Langdell had cocaine, diazapan and anti depressants in his system.
A post mortem of Katie’s body revealed bruises on her face, legs, trunk, vagina and anus.
The court heard that Langdell told Katie he was a lawyer who owned a law firm.
This was untrue and he in fact had been suffering mental health issues for the previous two years and had been admitted to psychiatric hospitals.
Defending Peter Benjamin Aina said: “He admits that he had the mind and body of a psychopath.
“He had sexual intercourse with her body using a bar of soap to aid vagina and anal penetration.
“It seems that the soap bar is what has caused the lacerations (to her anus and vagina).
“He accepts that he bit her nipples and having done that he took photos of her corpse.”
The court heard that Langdell had previously been in court for threatening to kill and then have sex with a young girl.
Langdell had been arrested in February 2015 after he told a mental health worker that he wanted to kill his girlfriend’s younger sister.
Benjamin Aina, defending, said Langdell told the worker he wanted to cut her throat, take her clothes off, see her naked and then have sex with her dead body.
He pleaded guilty to making threats to kill in March 2015 and given a nine month sentence suspended for two years.
