A man is sentenced to at least 22 years in prison for the murder of his 93-year-old friend. According to reports, the killing follows a period in which the defendant became gripped by paranoid delusions after using cannabis. The BBC reports that he tortures his friend over a roughly 24-hour period, and that the attack involved sustained abuse rather than a brief assault. The Mirror adds that during the final moments before his death, the victim speaks and names the person he describes as his “best friend.” The Mirror frames this as part of the evidence around the victim’s last words, which the court considers alongside other information about the events leading to the death. Both accounts describe a single incident in which the victim is subjected to prolonged torture and ultimately dies, and they agree on the overall sentence length of a minimum 22 years. Details about the precise charges and court findings beyond the sentence and the described conduct are not provided in the supplied text.
