Paul Kirby, ex-husband of Amanda Kirby, was the businessman who tricked Dr. Alan Grant back onto Isla Sorna to search for his son, Eric Kirby who disappeared on the island two months prior. Paul lied about being a millionaire businessman who owned the non-existent Kirby Enterprises to convince Alan Grant to join them. He admits later that he owned only a small business called Paint and Tile Plus at the West Gate Shopping Center in Enid, Oklahoma.
