Bad Wolf by Nele Neuhaus

When an unidentified teenager is found dead outside Frankfurt, the police are stumped about her identity, even weeks after the discovery of her body. Then, Chief Detective Superintendent Pia Kirchhoff and her colleagues find themselves investigating the brutal beating of television host Hanna Herzmann, who was left for dead in the trunk of a car. Could the two cases possibly be related? In this the sixth book of the Kirchhoff/Bodenstein series (but second to be published in the U.S.), Neuhaus writes a police procedural that is similar to the mysteries of Camilla Lackberg and Helene Tursten.
