Warren was a person playing paintball at Blue Sky Park. He wasn't very sporting as he howled at two of his friends to put them offguard. He showered them with paint before they even put their helmets on. When he heard the roars of the Smilodon he thought it was them trying to get him back. He was then torn apart by the creature. Nick Cutter examined his shredded remains later. (Episode 2.3)
