Back Story and Family Edit
Collin Murphy was a senior detective in the Chicago PD and an investigator in the Black Cat Department, covering the same territory as the modern-day S.I. department. When Karrin was 11, he committed suicide.
Karrin is a nominal Catholic, as is her family.
Personal Life Edit
In Summer Knight, it comes out that when she was seventeen years old, she married Gregory Taggart, who Harry Dresden estimates to be about a decade older. Some time later Taggart left her. They tried to reconcile a few times, but it always ended in fighting.
In Summer Knight, her ex-husband Gregory Taggart died, 43 years old, at night, after a long fight against cancer. He had not told Murphy about his illness, and she was devastated when learning of his death by discovering his obituary in the Tribune newspaper. She regretted not having been able to say good-bye.
In Blood Rites, Karrin revealed that she had been married to Rich at some point, but were divorced. He felt she was ignoring him for her job; she thought he wanted her to stay at home so she wouldn't make him look bad at work and was using the excuse of wanting to have kids as a rationalization. Murphy flipped when she found out that Rich is engaged to marry her kid sister, Lisa Murphy. At this time, Rich was a police detective in New Orleans and was getting transferred to the Chicago FBI to be near Lisa and her family.
In Proven Guilty, Rich (now called Rick) is an FBI agent called in to assist the Homocide Department in the SplatterCon!!! case by Detective Greene and aided him in questioning Molly. Karrin interceded. She does not get along with her ex-husband.
Regarding Jered KincaidEdit
In Small Favor, Karrin was very distraught over how badly wounded Kincaid is after engaging the Denarians at the Shedd Aquarium. Later, she said it hurt to see him that way, but she was not sure how involved she is. She thinks it's stupid to get hung up on him since he's not interested in getting serious. Harry believes it's that Karrin doesn't want to get close so that makes Kincaid safe to care for him. At the end, Karrin had an odd look on her face as she watched Kincaid, wounded, crawl in next to Ivy, also wounded, with his Glock and looking very paternal.
Regarding Harry DresdenEdit
In Proven Guilty, she admitted to being attracted to Harry, but was unwilling to act on it. First, she doesn't want to ruin their friendship and working relationship. Second, she worried about their difference in lifespans: as a wizard, Harry will live for centuries, and she wants someone who can grow old with her and raise a family.
In the SeriesEdit
In White Night, Murphy calls Dresden in on a murder case, she's a sergeant now and says she'll pay him herself. The victim was a practitioner whose death appears to be a suicide. Harry found evidence that only a Wizard could find and believes it's murder. They colaborated on the case and connected cases that led to uncovering a power struggle within the three Houses of the White Court. When Harry and Ramirez go to challenge a duel to Madrigal Raith and Vittorio Malvora at the White Court conclave in the Deeps. Murphy was part of Harry's team that was waiting in the Nevernever to be let for the anticipated big battle.
In the end of White Night, Harry reached into Murphy's bag to get his .44 gun and he saw a "boxy little machine gun". Murphy said its a P90 and that the magazine has clear plastic so you can always see how many rounds you have left. She got it in a box of Belgium chocolates from Kincaid the year before. The P90 made it's first appearance in the battle of the Deeps.
In Small Favor, she pushed her way into being a part of the Warden's meeting with the Denarians at the Shedd Aquarium. Then later, she insisted on assisting the rescue of The Archive (Ivy). She was with Thomas on his boat when they pulled Harry out of the water off the island of Demonreach (as yet unnamed). When Deirdre attacked Harry as he tried to get into the boat, she pulled her P-90 on the Denarian, but it was knocked out of her hands. Harry offered her Fidelacchius and when she draws it, it lights up blinding Deirdre, who disappeared under the water, allowing them to escape. Harry said he thought that the Sword lighting up was a job offer—she says she already has a job. At the end, Karrin talked with Harry more about the Sword.
In Turn Coat, Murphy helped Harry look over Morgan's file from the Council. She questioned why Morgan wasn't zapped by Aleron LaFortier's Death Curse and why there was not any evidence of magic. She suggested that Harry follow the money. She captured Binder easily.
By Ghost Story, she has a buzz cut and has become far more accustomed to dealing with the supernatural, leading the Chicago Alliance, a gathering of the Alphas, the Paranet, and Molly, backed by Marcone and the White Court.
In Ghost Story, since Harry died, she had become far more paranoid, granted it is justified.
Work Life Edit
Whenever something inexplicable happens that the Chicago PD must handle, they send it over to Special Investigations. Conveniently, this is also where they tend to transfer out-of-favor officers. Murphy, however, took the assignment so seriously that she hired a wizard on as a consultant, much to her coworkers' consternation. She uses Harry Dresden as a walking supernatural library, hiring him as a police consultant. 
At the end of Proven Guilty, Karrin Murphy was demoted to the rank of Detective Sergeant, after leaving the scene of the crime for 24 hours while she was on duty. She is partnered with Henry Rawlins. Rawlins knew Murphy's dad.
Abilities and Weapons Edit
- P-90 — clear plastic magazine to see how many rounds you have left.
- Two Japanese swords, one long and one short over the mantle 
- Sig 
In Harry's Sight, Karrin appeared as angel with glowing gold hair and eyes of azure flame. She carried a shaft of flame as a weapon. When Harry first Saw her in Fool Moon, she wears flawless white robes.
In Grave Peril, when Harry was helping Micky Malone, Harry Saw her as she entered the room with his Sight already opened. "The door burst open. Murphy came through it, her eyes living flames of azure blue, her hair a golden coronet around her. She held a blazing sword in her hand and she shone so bright and beautiful and terrifying in her anger that it was hard to see. The Sight, I realized, dimly. I was seeing her for who she was."
When Harry Saw her again in Blood Rites She appeared as an angel, her eyes were "azure flame", she bore a fiery shaft in her hands. Her robes had become smudged with filth, blood, and smoke. She bled from several wounds and moved like she was in terrible pain. 
In Small Favor, when Karrin was under attack by the Denarian, Deirdre, she drew the sword, Fidelacchius, from it's scabbard on Harry's shoulder. Brilliant white light shone from The Sword scaring off Deirdre. Harry said he believed that to a job offer, Karrin says she already has a job. Later she asked Harry more about it but still declined, as she has already sworn an oath to protect Chicago.
- Murphy might have descended from royalty. It is talked about in Small Favor that to be a knight of the cross, one might need to be a descendant of royalty, since in Changes, Murphy wielded Fidelacchius and now has it in her possession.
