History
Hackett was the bodyguard of Robert Queen, the CEO of Queen Consolidated.

In 2007, Hackett was on the Queen's Gambit, the Queen family's yacht along with Robert, his son Oliver Queen, Sara Lance and 4 other people. During the sail, the Gambit sank and Hackett was one of the 3 known survivors, along with Oliver and Robert (Sara Lance was thought to be dead but secretly survived). The 3 made it to a raft, and stayed there for a few days. However, when Robert realized that there is not enough food for the 3 of them, he shot Hackett in the head, killing him, before shooting himself in the head so that Oliver will survive. After the shot, Hackett's body fell into the water.
