Jurassic Park III
He was the airplane pilot who flew the plane with the Kirbys to find Eric Kirby on Isla Sorna. However, they have landed on the same island that had banned human interference known as Site B. After landing on the island, they are attacked by the Spinosaurus. He had been attacked by the Spinosaurus and abandoned Cooper after their first landing, but he lost control of the plane after it had slammed against the Spinosaurus, and it crashed into a forest. Then the Spinosaurus destroyed the airplane, pulling Nash out by his legs, steps on his back, and devoured him very messily. He had sacrificed himself to save Alan and his friends. The satellite phone he was carrying was found by Amanda Kirby in Spinosaurus dung, along with human bones and Cooper 's femur. His weapons included a Heckler and Koch SL8 fitted with a 10 round magazine and M68 Aimpoint red dot sight, and what looks like a Mossberg 500 Cruiser 12 gauge slinged over his back.
