Thousands of witches angered by the lenient sentence given to Stanford rapist Brock Turner have performed a mass hexing after organizing online.

Led by Melanie Elizabeth Hexen, from Iowa, the witches performed their hexing ceremony at 10pm Central Time yesterday, asking for Turner to be made impotent and suffer continuous pain.

Dozens of the group even posted pictures of the pagan shrines used in their rituals online, including ceremonial daggers, statuettes and even a candle 'dipped in menstrual blood'.

Witches angered by the six-month jail sentence handed to Stanford rapist Brock Turner, 20 (pictured), carried out a mass hexing ceremony yesterday night

Thousands of people took part in the ceremony, which asked for Turner to be struck with impotence and have the 'pain of pine needles in your guts', with dozens posting images of their shrines online

Hexen, who works as a bellydancer and midwife, but identifies herself on Facebook as a Priestess of Elder Craft, told US News that she originally created the event with her 12 coven sisters.

However, after the page got shared around it soon had thousands of people signing up to take part.

She said: 'I think it really struck a chord with a lot of women as a way to feel like they had some power in this situation.

'That there was something they could do, some way they could come together and focus their rage and their need for justice that wasn’t being met.'

'Witches doing spells in times when they’re otherwise powerless goes back thousands of years.'

As well as creating the event, Hexen posted instructions for the spellcasting ceremony online.

Followers were told to get a black candle, piece of string, and a representation of Brock Turner, noting that the candle could be anointed with 'urine, menstrual blood or hexing oil'.

Next, the hexers were told to draw a circle of power around themselves for protection - with salt being recommended as a good material - before marking 13 crosses on the candle and lighting it.

After raising power by 'running, screaming, clapping, or meditating', the witches were told to wrap the icon of Brock with the string and say: 'In the most holy name of Hecate, the Goddess of Life and Death, She who holds the key to the underworld, let this rapist meet justice. Let him be destroyed.

Melanie Elizabeth Hexen, from Iowa (left and right), who describes herself as a Priestess of Elder Craft, created the event and says there is no doubt in her mind that the curse will work

'Brock Allen Turner we hex you. You will be impotent. You will know constant pain of pine needles in your guts. Food will bring you no sustenance In water, your lungs will fail you

'Sleep will only bring nightmares. Shame will be your mantle. You will meet justice. My witchcraft is strong. Our witchcraft is powerful. The spell will work. So Mote it be.'

The witches were also told to target Dan Turner, Brock's father who has railed against his son's conviction, and Judge Aaron Persky, who presided over his trial.

Hexen added: 'I’m a really experienced, powerful witch. I have no doubt that when I cast a hex, it will be successful.'

There has been widespread outrage at Turner's case after he was sentenced to just six months in jail despite being convicted of raping a girl outside a frat house at Stanford University.

Turner was convicted in March of taking the girl from a frat party, partially stripping her, digitally penetrating her, and then dry-humping her unconscious body behind some dumpsters.

The attack only stopped when two Swedish students happened upon the scene causing Turner to flee before he was tackled to the ground and arrested.

Judge Persky, who oversaw the trial, and municipal judge Margaret Quinn, who wrote a letter supporting Turner, have since received threats over their part in the case.

Meanwhile Leslie Rasmussen, a school friend of Turner's, has rowed back on another letter she wrote to support the athlete, saying her statement has been 'misconstrued'.

Kerry Owens, a guidance counselor at Turner's high school and another of the 39 people to write letters in his favor, has also apologized for saying he was 'undeserving' of jail.

The anger at Turner's sentence has been compounded by statements written by the champion swimmer in which he refuses to apologize for his actions.

Turner has also repeatedly stated that he only regrets getting drunk on the night in question, while accepting no responsibility for the serious attack he carried out later in the night.

Meanwhile an impact statement from his victim, read out loud in court, has garnered millions of views as the 23-year-old offers a heartbreaking glimpse into the physical and emotional trauma the attack has left he suffering.

In it, she details the shock of being told she was attacked after waking up in the hospital, the extent of her injuries - both internal and external - and the torture of hearing Turner tell jurors that she enjoyed what he had done to her.

Despite the attention her words have generated, she has chosen to remain anonymous, saying today that she wants it to act as 'a statement'.

She said: 'I remain anonymous, yes to protect my identity. But it is also a statement, that all of these people are fighting for someone they don't know.

'That's the beauty of it. I don't need labels, categories, to prove I am worthy of respect, to prove that I should be listened to.
