Teen Killer Heard Voices: Trial Reveals Mental Battle

At Lincoln Crown Court, a chilling trial unfolded as jurors heard that the teenage defendant, aged 13 at the time, claimed to be hearing voices commanding her to harm others. She described feeling a loss of control over her own body, suggesting her actions were not entirely her own. This defense hinges on a severe mental disorder, as testified by a clinical psychologist who stated it substantially impaired her ability to form rational judgments.

The prosecution countered this by asserting the killing was premeditated murder, pointing to alleged planning and subsequent deception by the defendant. They presented evidence from psychiatric specialists who challenged the notion that poor mental health solely caused the actions. Pathologists detailed the horrific extent of the victim's injuries, reporting 143 sharp force wounds, including numerous strikes to the head and neck.
