French national stabbed a schoolgirl 20 times before watching the news on TV and confessing: " I think it was me, Mum."
Jessica Knight who was stabbed 20 times and left lying in a park
Kristofer Beddar launched a "savage" attack on 14-year-old Jessica Knight in a park in Astley Village, Chorley, Lancashire.
She was discovered with blood "squirting from her neck" in January this year but thanks to the help of a passer-by survived, a jury was told.
Preston Crown Court heard that Beddar, 21, of Daisy Hill Drive, Adlington, Chorley, was living with members of his English family at the time of the incident.
It is alleged that following the attack Beddar told his mother he thought he may have been the culprit.
Marion Beddar took her son to the local police station that night and told an officer at the counter: "This is my son. I have brought him in. He is responsible for the stabbing."
Beddar, who denies a charge of attempted murder, claims to have no recollection of the attack after drinking a half bottle of Jack Daniels that afternoon.
The court heard that Beddar did manage to text his mother minutes before or after the stabbing occurred, however, to inform her that he would not be home for tea.
Prosecuting, William Waldron QC, said: "The defendant accepts that in causing the injuries he did, there must have been an intention to cause serious harm to Jessica, but he denies he was attempting to murder her.
"The Crown rejects that denial. Our case is straightforward. The defendant's attack of amnesia for the critical moment is borne out of convenience and for no other reason."
The barrister added: "He had lost his temper for some reason or other as he was prone to do, and having done so perpetrated a frenzied attack upon Jessica Knight, being unable to stop once he had started."
Jessica, now 15, had finished school for the day and was walking through the park listening to her iPod on her way to meet a friend when she was attacked.
She was stabbed around 20 times and sustained life-threatening wounds to her neck, abdominal area and chest.
In an interview read out in court, Jessica told police she remembered very little about the attack but recalled being on the ground and feeling pain worse than she had ever experienced before.
"I had my eyes shut, it was total blank," she said.
The trial continues.
