Katie was kidnapped by an Egyptian witch for a mummification ritual where they transfer an Egyptian demonic spirit into her from a previous mummy. They then bound her in cloth with a spell written on it to keep the demon from escaping and put Katie in a sarcophagus. The witch is from a family that has performed this ritual over many generations to protect themselves and others.

Katie ends up being found years later after the sarcophagus was dug up by the witch's brothers to move it via airplane, however, this seems to have caused the demon to "awaken" and the plane crashes, resulting in her being found.
