A shocking new Netflix documentary reveals the harrowing true story of a teenage girl who was cyberbullied by her own mother, exposing the chilling messages she sent.

Unknown Number: The High School Catfish, released on Netflix on 29 August, explores the case of Lauryn Licari and her mother, Kendra.

In October 2020, Lauryn, then 13, and her boyfriend Owen McKenny began receiving alarming text messages from an unknown number. After initial suspicious messages suggesting Owen would break up with Lauryn, the harassment paused but resumed in September 2021.

The young couple was bombarded with 'hundreds of thousands' of abusive messages, with no clue as to who was behind them.

Everyone was stunned when the FBI identified the unexpected culprit - Lauryn's mother, Kendra.

The incident shook the small community of Beal City, Michigan, leading Netflix to create an entire show about it.

Kendra, 44, claimed she didn't send the initial texts about her daughter's relationship but confessed to continuing them once they resumed, revealing she spent one to eight hours a day texting Lauryn and Owen.

In the TV show, Kendra explained: "I started needing some answers, and then I just kept going. It was a spiral, a snowball effect. I didn't know how to stop.

"I was someone different in those moments. Mentally, I was in a terrible place. It felt like I was wearing a mask; I didn't even recognize myself."

In December 2022, Kendra was arrested and faced multiple charges of stalking and using a computer to commit a crime.

She pled guilty to two counts of stalking a minor and was sentenced to 19 months to five years in prison, with a release date set for 8 August 2024.

Licari has since expressed remorse for her actions, stating in the documentary that she is 'very disappointed' in herself and feels she has let herself and her family down (via Today.com).

In the documentary, some of the messages Lauryn received were unveiled, and they are truly shocking.

One text reads: "Hi Lauryn, Owen is breaking up with you. He no longer likes you and hasn't liked you for a while.

"It's clear he wants me. He laughs, smiles, and touches my hair. We are both down to f**k. You are a sweet girl, but I know I can give him what he wants, sorry, not sorry."

And another sent months later says: "How's the happy couple? Preparing for the end of a golden relationship? We hear about how you are the forever couple.

"Owen loves me, and I will always be the girl he loves. He will be with me while your lonely, ugly a** is alone."

On the show, Lauryn recalled receiving at least six text messages a day, with one saying: "Trash b****, don't wear leggings ain't no one want to see your anorexic flat a**."

Discussing the messages' devastating effects, she said: 'I would question what I'd wear to school. It definitely affected how I thought about myself."

As per MailOnline, other messages included: 'He thinks you're ugly', 'He thinks you're trash', and 'You're worthless'.

One particularly horrific message even instructed the teen to end her life, stating: "'Finish yourself or we will #bang."
