The mother of a schoolboy stabbed to death in Croydon says every teenage death prolongs her family's pain.
Fico Dougan was knifed through the chest in front of two teenage girls and a two-year-old toddler in September.
The Old Bailey heard the 17-year-old was the victim of a calculated and unprovoked attack.
Fico had never met his killer Urian Gardner.
Gardner, now 17, is today beginning a 14 year prison sentence for murder.
Fico's mum Sandra Opoku, told the Evening Standard: "After Fico died there's been nine or ten young people stabbed to death in London.
"Every time it happens it brings it all back."
