Devil's Claw by J. A. Jance

The report of a homicide at Cochise Stronghold in the Dragoon Mountains captures Joanna's full attention. An Indian woman has been found shot to death ... a woman recently released from prison after serving time for the manslaughter killing of her husband. And her fifteen-year-old daughter, Lucy, is missing. The death at first appears to be a case of exploding domestic rage, and a troubled teen runaway may be a victim -- or a cold blooded killer. Joanna's investigation leads her down a twisted trail of hatred and greed, where violence is the first response and long-buried secrets are a reason to kill ... or die.
