Rudy Gillen

Rudy Gillen is criminal psychologist who went to the same school as Dr. Kenzo Tenma. He is in constant correspondence with Dr. Julius Reichwein, his former professor, who wrote to him about Johan Liebert. Because Johan had connections with one of his patients, Gillen became interested in the young man and joined forces with Dr. Reichwein to prove Tenma's innocence.
