Leonardo Reid, 15, and Klevi Shekaj, 23, were stabbed in and around Elthorne Road at 11.30pm on June 29.
Post-mortem examinations confirmed both men died as a result of stab wounds to the chest.
Their families continue to be supported by officers from the Met's Specialist Crime Command.
A third man, aged 28, was also stabbed in the attack.
He was taken to hospital where his condition was assessed as not life-threatening.
