Q: Generate an appropriate single-sentence summary for the given text such that it includes the main topic of the text.
Cain Jackson, 24, died outside a property in Meadow Road, Rugby, after being attacked on 31 October. Eighteen-year-old Ethan Tucker, who lived on the same road where Mr Jackson was killed, denied his murder but pleaded guilty to manslaughter last month. He was sentenced to four years and four months at Warwick Crown Court on Friday. Tucker, who was 17 when Mr Jackson was killed, was arrested by Warwickshire Police on the night of the stabbing. At the time, the force said it was believed to have escalated from an altercation in the bridge area of Parkfield Road. Speaking after sentencing, Det Insp Teresa McKenna, from Warwickshire Police, said it was a "tragic event which led to a young man losing his life". She said officers' thoughts were "with Cain's friends and family at this difficult time". Follow BBC West Midlands on Facebook, Twitter and Instagram.
