Ruthless murder

While walking his dog, a man finds the corpse of a young woman in a pond under the Bohunik motorway feeder, through which the Čertík stream flows. The Brno police detectives discover that the woman was murdered in a particularly brutal manner - first strangled and then beaten to death with an iron bar. Moreover, she was a single mother raising a young daughter. Therefore, Colonel Motl does not need to encourage his men to find the perpetrators of this horrific crime as soon as possible.
