Annabelle Beatson Asiedu said her brother was 'addicted to achievement'
The sister of a 19-year-old DJ stabbed outside a London nightclub has said his death left their family with "irreparable damage".
Carl Beatson Asiedu, of Norbury, south London, died of stab wounds near Club Life in Goding Street, London Bridge, at 0500 BST on 1 August.
Police said the killing may have been provoked by jealousy.
In a witness appeal outside the nightclub his sister Annabelle spoke of the "void" left in their lives.
Ms Beatson Asiedu, 24, said: "Carl told me the week before he was taken from us he was going to be famous.
"He was allergic to being broke, addicted to achievement and success was his catalyst.
"He wanted to prove that with hard work and determination anyone from any background could achieve greatness."
Ms Beatson Asiedu added: "His premature and brutal murder has destroyed these aspirations."
Police found Mr Beatson Asiedu dying in the back of a car they stopped for jumping a red light.
The media production student at De Montfort University in Leicester had just performed a DJ set at Club Life.
Ms Beatson Asiedu added: "The irreparable damage and the void we now feel is indescribable.
"How can it be that parents should select a coffin for the baby of the family?"
Det Insp Chris Le Pere, of the Metropolitan Police, said: "He was very popular and it could be this popularity and success that resulted in murder, prompted by jealousy and envy.
"We need to catch whoever did this and ensure that they can't take another young life."
