Dortmund

Father Dortmund was a priest living in Los Angeles.

Before Trinity
Along with Frank Giggs, Sam Collins and Allen James Mulrooney, Dortmund was involved in the sexual abuse of several children, including Aaron Biehn, before Trinity.

Trinity
Don Biehn, accompanied by Jack Bauer, confronted Dortmund about the abuse of his son. Dortmund finally admitted to the molestation, and in his anger Biehn slit Dortmund's throat with a shard from his handcuffs. Jack managed to stabalise the priest long enough for Tony Almeida and an ambulance to arrive.
