Transgender paedophile who is too dangerous for a women’s prison will spend another 33 months behind bars after threatening to put warden’s genitals in a blender

A transgender pedophile has been given an additional 33 months in prison after he attacked guards and threatened to put one guard’s genitals in a blender.

Marcia Walker, 51, who is deemed too dangerous for a women’s prison after raping two young girls, left a series of vile voicemail messages threatening to kill and harm prison staff.

She also called Crimestoppers from HMP Frankland in Durham – known as the Monster Mansion for its many murderers, rapists and terrorists – falsely claiming there was a bomb in the staff car park.

A prison source said Walker is a “problem” and should be isolated from everyone.

“She’s making it hard on herself,” the source said. “If she just interacted with people, her time inside would go by a lot faster.”

Walker’s fellow inmates in the prison (seen from above) include terrorist Michael Adebolajo, who murdered soldier Lee Rigby, serial killer Levi Bellfield, who murdered schoolgirl Milly Dowler, and former police officer Wayne Couzens, who kidnapped, raped and murdered Sarah Everard.

Guildford Crown Court heard that Walker sent shocking voicemail messages in which he threatened to cut off a man’s penis, put his genitals in a blender, lock the brakes on his car, set his house on fire and plant a bomb under his car.

She sent more threatening voicemails, letters and emails to staff, one promising to shoot a guard and other emails making disgusting, racist comments.

On January 24, Walker called Crimestoppers from Category-A HMP Frankland, in County Durham, with the ‘intention to… create a false belief that a bomb was present in the staff car park’ at the prison.

And she assaulted two prison guards in Frankland.

She was charged with two counts of racially aggravated public disorder, for which she was sentenced to an additional 18 weeks in prison.

Two charges of assault on an emergency worker earned her an additional 31 weeks in prison.

Two charges of sending malicious communications resulted in an additional year in prison.

Walker also admitted to deliberately providing false information about the bomb, for which she received a six-month sentence.

And because she sent a message threatening serious danger, she has to spend an additional two years and three months in prison.

A number of sentences, which were pronounced on August 20, were imposed concurrently, bringing the total sentence to 33 months.

One further charge, sexually abusing a man, was dropped.

HMP Frankland is home to some of Britain’s worst criminals, including terrorist Michael Adebolajo, who murdered soldier Lee Rigby on a street in Greenwich, serial killer Levi Bellfield, who murdered schoolgirl Milly Dowler, and former police officer Wayne Couzens, who kidnapped, raped and murdered Sarah Everard.

Walker was first sentenced to 13 years in prison in 2003 after raping two girls, one of whom was four years old.

Formerly known as Mark Walker, she is legally recognised as a woman by prison authorities, but has long been embroiled in a dispute over the possibility of undergoing gender reassignment surgery.

In 2021, Durham Crown Court heard that Walker attacked security guards after they objected to her carrying razor blades.

She claimed that not being able to shave made her gender dysphoria worse. When prison officers entered her cell, she spat at one of them and said: ‘I have Covid.’

The court heard Walker was already angry because copies of National Geographic magazine – sent to the prison by a charity – had been seized from her cell because they contained pictures of naked children.

During the interview, Walker had maintained that she had no sexual interest in the images in the magazine. She added: ‘They can’t take my razors away from me.’

Fiona Lamb, for Walker, said at the time: ‘The defendant has had a very unpleasant experience in custody. I’m sure no one enjoys it, but due to the defendant’s personal circumstances it has been very difficult for her.’

Despite her decision to identify as female, prison administrators determined that Walker would pose a risk if transferred to a women’s prison and held in isolation.

Other inmates were “furious” at being locked in their cells for 45 minutes so Walker could wash and eat alone.

A source said: ‘She must be treated as a woman but cannot be moved to a women’s prison because she poses a risk.

“And because she is legally a woman, she must be kept separate from male prisoners.”

The prison service said: ‘Transgender prisoners do not receive special treatment and have access to the same facilities as male prisoners.’
