A schoolgirl accused of the attempted murder of her friend at school told police she had become ‘unhappy and began self-harming’ after she was sent ‘rude and suggestive’ messages on social media.
The teenager, who was ‘obsessed with serial killers and school shootings’, is accused of luring her friend to a quiet part of the Hampshire school grounds where she stabbed her with a kitchen knife, causing a minor wound to her chest, on April 25.
The defendant, who was 14 at the time of the attack, said in a police interview read to her trial at Winchester Crown Court, that the ‘attempt was not to kill’ but admitted she stabbed her.
She said she had suspected that the victim had been responsible for creating false social media accounts, including a Tumblr blog, under the defendant’s identity and posted photos of her and her home on it.
She said the photos were screenshots of Snapchat messages she had sent. The victim has denied being involved.
The defendant said the posts on Instagram and the 4chan forum led to her receiving ‘rude and suggestive’ messages from strangers, including on Kik messenger.
The defendant said the messages sent during the previous summer only stopped when she deleted all of her social media accounts.
She said: ‘It made me really, really unhappy; that was when I started doing self-inflicted wounds, I didn’t talk to anyone about it.
‘It makes me nervous, gives me butterflies in my stomach, I remember how much it hurt that someone would do it. I felt I couldn’t trust anyone, I couldn’t talk to anybody as they could be a possible person who did it.’
The defendant said she could not explain why she carried out the attack.
The court has heard that the defendant had carried out internet research on fatal stab wounds.
She said: ‘Nothing has happened between me and her which would have set it off, nothing has triggered it, whenever I am around her I feel uneasy and I can’t trust her.’
She added that she had been having thoughts about hurting people and said: ‘I wouldn’t really call it an urge, today is the exception, it’s been thoughts, not like killing, but maiming them, I’m not sure why.’
The defendant said she was not ‘influenced’ by serial killers but was only interested in them.
She described how she had created a project for her fashion GCSE on the subject of identity which was set around serial killers Ted Bundy and Richard Ramirez.
She said: ‘I thought it was cool and edgy but I wouldn’t say I was obsessed.’
The defendant added that she had also been interested in ‘quite dark stuff’ including online videos including an Islamic State film and one of a man mutilating himself.
The defendant, who is now 15, denies charges of attempted murder and wounding with intent. She has pleaded guilty to unlawful wounding and possession of a bladed article on school premises.
The trial continues.
