A schoolgirl who filmed herself as she tried to strangle and stab her parents at their Cambridgeshire home has been cleared of their attempted murders.
The 16-year-old girl was, however, convicted of attempting to choke her mother with intent and unlawfully attempting to wound her father.
Jurors were shown the video - filmed at the family's home in St Neots - during a trial at Cambridge Crown Court.
The girl was remanded to a psychiatric unit for the preparation of reports.
During the trial the teenager claimed a voice in her head had told her to carry out the attacks.
She told jurors the voice had ordered her to kill her parents saying: "Do it, do it".
The girl, who cannot be named for legal reasons, told the court the voice "showed me what it wanted me to do".
She added: "It was just an image in my head, my mother with a noose around her neck, my dad with a knife in his chest."
The youngster, who was 15 at the time of the attacks, said she had experienced voices before the attack, which happened in her parents' living room last February.
She said she needed her parents to see something was wrong but had never intended to kill them.
The jury heard how after an argument between the teenager and her father, the girl went upstairs to her bedroom.
It was there that she put on a nightgown, applied make-up and then filmed herself as she talked about her plans to kill her parents, the court heard.
The jury heard how she had a noose made from dressing gown cords, with which she planned to strangle her mother, and had a pair of scissors with which to stab her father.
John Farmer, prosecuting, said the only reason the girl did not succeed was that the scissors she used were not sharp enough and her father was not harmed and was able to grab them from her.
The teenager said she had begun to hear voices in her head when she was in Year Eight at school.
She also said she suffered hallucinations and, as a result, had received counselling at school.
