Frozen Moment by Camilla Ceder

Lars Waltz, owner of a car repair shop has been shot to death then run over repeatedly. In the course of investigating the crime, the police discover that another man, Olof Bart, was killed the same way as Waltz and that the bullets used in both crimes came from the same gun. Detective Christian Tell and his team devote their time to finding a connection between the two men, which they hope will lead to finding the murderer. Frozen Moment is the first novel by Camilla Ceder and is similar to Swedish mystery series by Ake Edwardson and Hakan Nesser. It hasn't been published in the U.S. yet though.
