19 year old Joseph Burke-Monerville died from a gunshot wound to the head, a post mortem has shown.
The student, from the Islington area, died at about 11.10pm on Saturday. A second victim is in a serious but stable condition.
He had spoken on Facebook of his excitement about a planned holiday to Magaluf on the Spanish island of Majorca next week, which he said would be "a week 'off' stress".
He was a past student of Aloysius' Roman Catholic College in Highgate and Wesley High School in Otukpo, Nassarawa, Nigeria.
Police are appealing for information on two suspects - one black, one light skinned - seen running from the scene towards the Pembury Estate.
