Summary

Two 21-year-old twin brothers, Eric and Sean Farrell, who had no prior criminal history, were sentenced to six years in prison for the manslaughter of Nicolae Diaconu (45) during a domestic incident. The court heard that the twins stabbed Diaconu eight times and struck him with a blunt object after he became abusive towards their mother, leading her to seek refuge. Mr Justice Tony Hunt noted that the incident occurred out of the blue and that the twins acted under a mistaken belief they were under threat. The judge imposed a seven-year and six-month sentence with the final 18 months suspended for the rest of their lives. The twins had previously pleaded not guilty to murder but guilty to manslaughter. CCTV footage showed them being amicable with Diaconu before the incident. The court considered mitigating factors such as their youth, remorse, and lack of previous convictions. The judge emphasized the level of violence and the use of knives and a hammer as aggravating factors.
