 Jurassic Park 's computer programmer , Dennis Nedry , has been bribed by Dodgson , a man involved with a corporate rival , to steal dinosaur embryos . Nedry deactivates the park 's security system to gain access to the embryo storage room . Nedry stores the embryos inside a canister disguised as <unk> shaving cream , supplied by Dodgson . Because of Nedry , the power goes out and the tour vehicles become stuck . Most of the park 's electric fences are deactivated as well , allowing the Tyrannosaurus to escape and attack the tour group . Grant , Lex , and Tim escape while the Tyrannosaurus injures Malcolm and devours Gennaro . On his way to deliver the embryos to the island 's docks , Nedry becomes lost in the rain , crashes his Jeep , and is killed by a Dilophosaurus .
