36 year old Earl Morin-Briton stabbed 32-year-old Theo Porteous three times in an unprovoked attack in Battersea car park in 2023.
Earl has been convicted of murder and knife sentenced to life with a minimum of 27 years.
CCTV footage captured the attack and helped police track Morin-Briton, who was arrested in Norwood just over a week later.
