Detective David Mills is a homicide detective that worked on the John Doe murder case. Before he submitted a transfer to a large city, Detective Mills served his first five years as a police detective in a rural area upstate when the work became too unsatisfactory – he hardly ever had any murder cases. After moving, he's partnered with soon-to-be-retiring, Detective Lieutenant William Somerset, ironically, Somerset's last case is Mills' first. David is like the polar opposite of William; Somerset is reserved, thorough, and disillusioned while Mills is impulsive, fiery, and idealistic.

Detective Mills is the husband of the late Tracy Mills, who was his high school sweetheart, who was murdered by John Doe who envied his "normal" life, and the father of the late unborn child Tracy was carrying. Tracy claims that she knew after their first date that he would one day be her husband and he would like kids, Tracy used to be on board with that too, but she fears this city is no place to raise a child, to which she was right. Tracy discloses to Somerset that she is pregnant and has yet to inform him.

After hearing John Doe killed his wife, Detective Mills was emotionally distraught, John wanted him to take vengeance, by becoming the seventh and final sin, Wrath. Somerset desperately tries to convince him not to but when Doe reveals that Tracy was pregnant, Mills couldn't contain his fury and shot him to death. Mills later became catatonic and taken away by police, the police captain reassures Somerset that Mills will be taken care of.

After the events of the John Doe case, Detective Mills has been prescribed with medication over the past years. When heard of an organization, known as the Anti-Hunters, Detective Mills became severely obsessed with them, mostly Wolf Shadow Hunter, even after being suspended it only amplifies his obsession to stop killers like them. Detective Mills investigation later puts him in the spot to face his obsession, however, even after passing he commits suicide moments after.

David's the husband of the late Tracy Mills and the father of their unborn child.



David Mills wants to make a difference in the world. He fought to be assigned to a busier area, so that he could work big cases. He is dedicated and highly motivated, though a little over his head, he is idealistic and ambitious.

He is by nature hotheaded and impatient. He is prone to losing his temper and acting out violently when frustrated. As Somerset puts it, he feeds off his emotions. Though this does not always serve him well, it also makes him physically courageous and a very dogged adversary.

David is naive and impulsive as Somerset considers Mills a little bit inexperienced, even though he previously worked as a homicide detective for five years. Whether Mills wants to make a name for himself or simply cure small-town boredom, its clear that David wants to see action.

According to his wife, Tracy, David was, and is, the funniest man she ever met.

Mills isn’t afraid to act or to speak his mind but that trait could get him into trouble even when a twisted killer starts taking a personal interest in him.

David Mills is younger and more athletic than his counterpart, Somerset, and as a result he is more prone to physical action. He states that he has been involved in at least one shootout while on the job, and mentions other accomplishments. His physical stats are impressive for an essentially average guy. He engages in a long foot chase and running gun battle with John Doe, and shows considerable speed and ability.

After the ordeal, David received psychiatric evaluation, however, he didn't help him as he became depressed that he was given prescription anti-depressions. Soon enough, David became obsessive with a new case involving numerous killings, David would stop at nothing to prevent the same mistakes, however, his obsession only made difficult for his sense of judgement, making him more prone impulses, and choosing to apprehend them instead of saving civilians, he would used every available resource to capture them, which destroyed his life, got him suspended from the force, including the cost of his new partner.
