Spears was an Asset Containment Unit trooper at Jurassic World on Isla Nublar in 2015. His team included himself, Austin (his commander), Miller and Cooper. His team was sent in to recapture the escaped Indominus rex.
When the 2 teams reached its last-recorded location, they discovered that the hybrid had torn out its tracking-implant. While the other team's commander, Katashi Hamada was inspecting the implant, the Indominus revealed itself to be camouflaging and seized Hamada.The 2 teams managed to stun the hybrid with their cattle-prods and taser-rifles, causing it to drop Hamada, but it proceeded to crush him underfoot.
Spears, Craig, Meyers, and Lee attempted to stun the hybrid with their cattle-prods and taser-rifles, but this attempt failed when Cooper was killed. Spears and Craig attempted to escape, however, the hybrid still proceeded to seize Craig and throw him backwards at a tree branch. After Lee was crushed by a falling log, the hybrid managed to tear off the net Austin had fired at it. Upon seeing this, Spears attempted to escape, but the hybrid grabbed him in its jaws and tore him apart behind some foliage, before eating him.
