While on the run, Gray and Zach come across a helmet with a claw rip and a crashed Jeep. (I recall the Jeep being a roofless blue Jeep, matching the color scheme of the new Jurassic World park).
The Jeep is found away from the main park,
not too far from the ruins of the original park.
Whose helmet/Jeep did they find?
(note: I don't expect anyone to be able to identify them by name - even just "one of this group of staff" sort of answer is fine)
