The public prosecutor general's office in Munich on Monday took over the investigation into the stabbing deaths of two Ukrainian men in southern Germany because of a possible political motivation for the crime, German news agency dpa reported. The two Ukrainians, who were 23 and 36 years old and lived in the southern German county of Garmisch-Partenkirchen, were killed at a shopping center in the village of Murnau in Upper Bavaria on Saturday evening. The public prosecutor general's office usually takes over investigations from regular prosecutors if there is a possible political motive for a crime.
