They were due to leave her alone with a medic who administered her three injections at around 5.30pm but are understood to have stayed for at least an extra half-hour.

The scheduled start of the procedure is believed to have begun around 6.30pm local time.

Geronimo waged a lengthy legal fight to try to get judges to block his daughter’s euthanasia request with the support of a Valladolid-based ultraconservative group called Christian Lawyers.

But Noelia, who spoke openly about her decision to end the mental and physical pain she has suffered for years during a Spanish TV interview earlier this week, said she wanted to “leave in peace”.

She was alone in the room when she died at her own request, apart from the doctor administering her injections.

In a Tuesday interview on Spain’s national Antena 3 station, Noelia admitted: “None of my family support me but the happiness of a father does not have to be above that of a daughter or above a daughter’s life.

“I just want to go in peace and stop suffering.”

Revealing how she wanted to leave this world, she added: “I’ve always thought I want to die beautiful.

“I’ll put on my prettiest dress and make-up.”

Supporters gathered outside the Spanish hospital where Noelia’s life ended, in a last-ditch attempt to change her mind.

Her mother, Yolanda said: “I am not in favour of euthanasia, of course I am not in favour, but I will always be by her side until the very last moment, as long as she allows me.”

In a heartbreaking final interview, she revealed: “I’ve been praying and thinking… hoping that at the last moment she’ll say ‘I regret it’.”

The distraught mum gave one last plea for her daughter to change her mind, reading aloud offers of financial help to get her daughter new treatments.

One email read: “Perhaps with significant help, she could begin to rebuild her life little by little.”

Yolanda added: “These are my final words.

“There’s nothing more I can do. If you decide to go ahead, I’ll be there for you, but if you change your mind, I’ll be there for the good times too.”

Noelia’s life began derailing after her parents divorced when she was a child and she was already receiving psychiatric treatment as a 13-year-old.

She ended up in care and suffered two sexual assaults, the last one a gang rape by three boys in a nightclub.

The harrowing attack, which Noelia has admitted she didn’t report to police, led to her October 4, 2022 suicide attempt, leaving her with a serious and irreversible spinal cord injury.

She uses a wheelchair to get around and suffers from excruciating leg and back pain which she says makes sleep difficult.

Noelia has admitted to suffering from a borderline personality disorder and another compulsive obsessive one.

The 25-year-old was “relying on the Spanish mental healthcare system” before she was raped, her family said.

Her condition was deemed “serious, chronic and disabling” under Spain‘s landmark 2021 euthanasia laws.

Noelia’s dad, supported by conservative advocacy group Abogados Cristianos (Christian Lawyers), argued that his daughter’s mental health was affecting her ability to make a free and informed decision.

But judges have insisted her mental faculties are “intact”, making her dramatic decision “free, conscious and informed” in line with the Spanish law on euthanasia.

Noelia eventually got the go ahead for her euthanasia from the European Court of Human Rights.

She said on Spanish TV earlier this week: “Before requesting euthanasia, I saw my world as very dark.”

“I had no goals or objectives.

“I have always felt alone, I have never felt understood, and no one has ever empathized with me.”

Questioning her dad’s decisions which delayed her euthanasia wish, she added: “He has not respected my decision and never will.”

Christian Lawyers, the organisation which has been representing Noelia’s dad, said in a statement released around 7pm UK time: “Noelia has already been euthanized.

“We deeply regret her death and denounce that this case highlights the serious flaws in the euthanasia law, which does not protect the most vulnerable people.

“Thanks to everyone who has empathized with the family during these very difficult times.

“You can understand that the parents are broken after years of trying to support her in her rehabilitation.”

But sympathiser Carla Gomez said: “Rest in peace and to those who don’t like Noelia’s decision, lump it.

“It’s her life and she has the right to decide.”

In June 2021, Spain became the fourth European Union country to legalise euthanasia and assisted suicide for people with incurable or severely debilitating conditions who wish to end their lives.

Spanish law states that applicants who are over 18-years-old with “chronic or invalidating suffering” can choose to receive assisted dying.
