In the case of the shooting of two walkers in Cologne, the police are examining whether it is a targeted murder in the rocker milieu. A 35-year-old man and his 28-year-old companion were attacked by several unknown persons on Saturday at 15:30 p.m. in Cologne's Böckingpark. While the woman suffered life-threatening gunshot wounds, the 35-year-old was killed.

According to media reports, the victim is said to be a former Hells Angels rocker. The investigators referred on Sunday only to the information from Saturday, according to which the homicide squad is examining possible references to the rocker milieu.

In order not to jeopardize the investigation, no further information could be provided, said a spokeswoman for the Cologne public prosecutor's office on Sunday on request.

According to the "Bild" newspaper, three darkly dressed men had watched the couple in the park. While the woman had been gunned down on the spot, the 35-year-old had fled on foot. After about 100 meters, however, his alleged killers caught up with him and killed him with a shot in the back of the head.

According to the "Kölner Stadt-Anzeiger", this bloody deed took place in the backyard of a brewery, where the 35-year-old is said to have run. Photos show that the police had blocked off a footpath leading into the park with flutter tape and traces were secured there. There, according to the "Kölner Stadt-Anzeiger", an employee of the brewery is said to have given first aid to the seriously injured woman.
