Chris Amador was an FBI agent and colleague of Stan Beeman. He served in Vietnam, and had "no wife, no kids, no pets, no hobbies." Amador was an unabashed womanizer, but seemed to have a genuine soft spot for his co-worker Martha Hanson.
When Martha turns down his request to resume their relationship, Amador begins unauthorized surveillance on her. Cornering Phillip outside her apartment one morning, he attempts to arrest him, despite having no grounds. When Phillip resists, Amador brandishes a knife; Phillip stabs him with it as they struggle. Phillip throws Chris in the trunk of his car and takes him to a safe house where he is given medical treatment by the Jennings, who try to keep him alive and hope to get information out of him.
