The night Zion died he was at the party with about 80 other youths - held at a house rented through Airbnb on Medbury Terrace.
Zion's funeral was scheduled for Friday 20 August, days after the country was put back into a national lockdown in a bid to prevent the spread of the Delta variant of Covid-19.
His family said they did not want to speak to media about his death.
Zion's girlfriend took to social media to pay an emotional tribute to the slain teen.
"I'm so weak at this point, I feel so lost nothing will ever be the same," said the teen - who the Herald will not identify - in a lengthy Instagram post.
"It feels like I lost the best part of me, from the beginning you held it down and stayed loyal - I wish I could've held you tighter the last time I saw you and told you how much you meant to me.
