About 30 people were gathered on the deck before the ledger gave way collapsing to the ground.
9-year-old Dariel Sosa and his 13-year-old cousin Jason Huerta were playing on the second floor balcony on Brighton Avenue in Perth Amboy when it gave way and they fell to the ground.
Investigators say the 9-year-old boy who lives there was playing with a 13-year-old friend from down the block. Adults were inside, and the kids were on the balcony.
