Daughter of murdered Sandy Hook principal pens heartbreaking letter to mom on anniversary

The daughter of the Sandy Hook Elementary School principal, who was tragically killed in the 2012 massacre, has penned a heartbreaking letter to her mom as she battles cancer.

Erica Lafferty was just 27 when her mother, Dawn Lafferty Hochsprung, was taken from her in the horrific shooting at Sandy Hook Elementary School in Connecticut, which claimed the lives of 26 people, including 20 children.

In April, Lafferty was diagnosed with Stage II Orbital Lymphoma and has been courageously fighting the disease ever since, accumulating thousands of dollars in medical bills and even starting a fundraiser to help cover the costs.

On Tuesday, marking the 11th anniversary of the school shooting, Lafferty shared an emotional letter she had written to her late mother on social media.

She wrote: 'Mommy, It's been 11 years since I've seen your face. Eleven years since I've been able to give you a hug or hear you and Sissy make fun of me for being ... well, me.

'I hate that you're missing all of this. I hate that I can't call you and tell you how terrified I am of these tumors that are spreading all over and eating my body alive.

'I want to lay in bed with you and just cry it out. I want to tell you the whole truth about how it feels, I want to talk to the one person in the world that I didn't have to hold a brave face for.

'I want to tell you about how crazy unfair and broken our health care system is and how scared I am that Steve and I will not be able to afford to keep me alive.

'I want to hear you tell me that we will be OK and that we will figure something out because we have no other choice. I want your love and your reassurance,' said Lafferty, whose mother was tragically killed on December 12, 2012.

Her mum was among the 20 six and seven year olds and five teachers who were murdered when a 20 year old man, Adam Lanza, stormed into the school and opened fire with a semi-automatic rifle.

Hochsprung, Lafferty's mother, was in a meeting with other senior staff when the horrific incident occurred.

Upon hearing shots but unaware of what they were, Hochsprung went to investigate alongside two other staff members and was fatally shot.

School therapist Diane Day, who was present at the time, later stated: 'They didn't think twice about confronting or seeing what was going on.'

Lanza took his own life after the shooting spree. He had earlier killed his own mother in her bed before heading to the school.

Despite investigations, a motive for the massacre was never established, but it was known that Lanza suffered from mental health issues including anxiety and anorexia.

He also had developed an obsession with mass murders and rarely left his room or socialised.

Lafferty's medical fundraiser has now raised over $192,000, but the mother-of-three expressed: 'There has not been one single day that I haven't worried about how I'm going to pay to stay alive.'

In another twist, controversial conspiracy theorist, Alex Jones, owes her over $100million after she and the families of other Sandy Hook victims won a lawsuit against him.

Jones was told to pay damages after he spread a conspiracy theory that the massacre never happened. He claimed the shooting was a 'false flag' operation by the US government to enforce gun control laws.

Victims' relatives spoke in court about being harassed and threatened by Jones's followers, who sent threats and even confronted the grieving families in person, accusing them of being 'crisis actors' whose children never existed.

The families won nearly $1.5 billion in judgments against Jones last year after he repeatedly promoted the false theory. However, they haven't received any of the money awarded to them by the juries.

Jones filed for bankruptcy last year, just months after being ordered to pay $950m in compensation and an additional $473m in punitive damages.
