A teenager has been jailed for at least 35 years for murdering two sisters as part of a Satanic blood pact.

Danyal Hussein, 19, savagely stabbed Bibaa Henry, 46, and Nicole Smallman, 27, to death in a Wembley park in June last year.

The Old Bailey heard he had embarked on a “campaign of vengeance” against random women in a failed bid to win the Mega Millions Super Jackpot lottery prize of £321 million.

Police tracked him down through DNA and uncovered a handwritten pledge to a demonic entity called King Lucifuge Rofocale to kill six women every six months, which was signed in blood.

Hussein declined to give evidence in his trial, claiming he was not responsible for the killings or for writing the pact.

He was found guilty of two counts of murder and possession of a knife.

Following Hussein’s conviction in July, the sisters’ mother, the Venerable Mina Smallman, said she had “never come across such evil”.

On Thursday, Hussein appeared in court by video link from Belmarsh top security jail for “Covid reasons” while the sisters’ family sat in court.

Mrs Justice Whipple sentenced Hussein to life in prison with a minimum term of 35 years.

She told Hussein: “In the early hours of Saturday June 6 2020 you brutally murdered Nicole Smallman and Bibaa Henry.

“You had found these two women. You were a stranger to them. You surprised them, you terrified them and you killed them.”

She said Hussein had dragged the bodies away and posed them in an embrace to “defile” them in death.

The judge said the lives of his victims’ loved ones had been “shattered”.

She referred to a victim impact statement by the sisters’ mother who described being “haunted” by the knowledge of how her children suffered.

On the pact with the devil, the judge said: “I am sure you performed these murders as part of that bargain for wealth and power.”

As “bizarre” as the pact seemed, it was part of his belief system, she added.

She told Hussein: “You committed these vicious attacks. You did it to kill. You did it for money and a misguided pursuit of power.”

The defendant sat facing away from the court as he was sentenced.

Earlier, prosecutor Oliver Glasgow QC ruled out a whole life order for Hussein because of his age.

Mr Glasgow said there were “significant” aggravating features, included taking a knife to the scene and destruction of evidence.

He said: “His offending is a product of his belief in Satanism and his belief you could enter into a bargain with a devil.

“That belief system is something he researched for some time.”

In preparation for the killing, Hussein bought knives from Asda and a black balaclava on Amazon and signed up to a lottery betting website.

In the early hours of June 6 last year, he stalked his victims as they celebrated Ms Henry’s birthday in Fryent Country Park in Wembley, north London.

Hussein stabbed Ms Henry eight times, before he slashed Ms Smallman 28 times as she bravely fought back.

He then dragged them into bushes where they lay undiscovered for 36 hours.

During the savage attack, Hussein cut his right hand with the 12cm knife, which he dropped in the grass.

Over the next 10 days, Hussein spent £162.88 on lottery tickets and bets – all without success.

On the evening of June 6, the sisters’ worried loved ones reported them missing, but officers were not deployed to the park until the next day.

Before they arrived, Ms Smallman’s frantic boyfriend Adam Stone, who could not believe she would have left their pet bearded dragon unattended, found the bodies.

Officers then carried out a painstaking search and identified the DNA of an unknown male from blood on the knife, bodies and surrounding scene.

On June 30 last year, in a major breakthrough, a DNA familial link was made to Hussein’s father, who had a past caution.

Within an hour-and-a-half, Hussein was identified on CCTV buying knives in Asda and returning home after the murders.

Searches of his bedroom in south-east London uncovered a book of spells, handwritten demon symbols and two blood pacts.

Jurors were not told of the extent of Hussein’s obsession with demons, spells and potions.

He had come to the attention of police aged just 15 over fears he was vulnerable to radicalisation and violent extremism.

Before the killings, Hussein communicated with others about demons and love potions, and carried out online research about the far-right and Norse mythology.

It is believed he was influenced by the work of an American black magician who has links with a British-based Nazi Satanist group known as the Order of Nine Angles.

Last week, Facebook removed his page and Instagram account and YouTube launched a review.

Two police constables have been charged with misconduct in public office after allegedly sharing pictures of the crime scene on WhatsApp, and are due to enter pleas on November 2.

Separately, the Independent Office of Police Complaints concluded its investigation over the response to the initial missing persons reports.

On Monday, the police watchdog found the level of service provided by the Met over the weekend when the sisters went missing was “below the standard that it should have been”.

A Satanist whose work is believed to have influenced double killer Danyal Hussein has been removed from Facebook and Instagram following an investigation by the PA news agency.

Hussein, 19, stabbed sisters Bibaa Henry, 46, and Nicole Smallman, 27, to death in a Wembley park after making a blood pact with a demon.

Since his Old Bailey trial, it has emerged that he was an active member of online forum Becoming A Living God, set up by black magician E A Koetting.

Parts of Hussein’s pledge to “sacrifice” women for power and wealth appeared to have come from the US author’s work.

Yet Koetting continued to promote his books to more than 200,000 followers on Facebook and YouTube.

Following PA’s investigation with the Centre for Analysis of the Radical Right (C4ARR), Facebook said it had removed Koetting’s page and Instagram account for violating its dangerous individuals and organisations policies.

On Wednesday, YouTube issued a statement to say it was “reviewing” the content.

The company stated: “Hate has no place on YouTube, and we are deeply saddened by this terrible incident.

“We have strict policies to ensure that our platform is not used to incite violence and we are in the process of carefully reviewing the content against these stringent rules.”

Professor Matthew Feldman, director of C4ARR, said some of Koetting’s work could amount to incitement to murder.

He said: “This is the best example I have come across of someone saying this is what you must do to become strong, powerful, rich.

“He has 87,000 YouTube subscribers and 128,000 on Facebook.”

“If 0.1% of people take that seriously, as Danyal Hussein clearly did, and think this is what I have to do to become famous, that’s 200 potential murderers.”

In his blood pact to King Lucifuge Rofocale, Hussein had pledged to “sacrifice” six women every six months to win a lottery jackpot.

Professor Feldman said Koetting had written about blood sacrifices to become rich, attractive and powerful – and even named the same demon, Lucifuge Rofocale.

His texts have also highlighted motiveless killing and making a blood pact.

Professor Feldman went on: “Koetting’s written works include texts that openly discuss and encourage murder.

“One book, Works Of Darkness, describes how to murder another person with a knife in a ritual sacrifice.

“Another book, Apex Of Eternity, advises people to study the terrorist handbook, provides practical guidance on how to kill another person.”

It quotes child murderer Ian Brady saying: “Always remember the first rule of murder: never kill a person that you have a reason to kill.”

One passage says: “What we’re looking for is the knowledge and skill needed to kill with any weapon, with no weapon and from a distance (as with explosives or traps).”

Professor Feldman said: “The text, in particular paragraphs and taken as a whole, can act as an incitement to murder.”

Apex Of Eternity was written for a Nazi Satanist organisation called Tempel ov Blood (sic), which has been cited as a major influence in seven recent UK terrorism prosecutions, six of which involved teenagers.

Tempel ov Blood is said to be the US branch of the UK-based Nazi Satanist group Order of Nine Angles (O9A).

In an apparent reference to Tempel ov Blood, Koetting wrote in one of his books that he joined “an American cell of the notorious British Order of Nine Angles”.

In a YouTube video, which has been viewed more than 17,000 times, Koetting discusses human sacrifice.

He says: “When you destroy the victim there is a release, a massive explosion of power and energy.

“If you can harness that and push it towards a goal, it’s powerful beyond most other forms of magic. It’s the blackest magic without a doubt.”

Later, he adds a caveat that he does not advocate harming anyone “to cover myself legally”.

Koetting follows a malignant form of Satanism called the Left-Hand Path, which grew out of the non-violent Right-Hand Path, which generally promotes white magic like ouija boards.

This summer also saw another double murder in Russia allegedly linked to a Satanist sect.

Professor Feldman suggested more could be done to support moderators of online content, and social media firms should “deep dive” into the background of figures like Koetting when they reach 10,000 followers.
