Berlin - Police captured Germany's most wanted man, Dieter Zurwehme (57) in Greifswald yesterday, after a passer-by spotted him in the street. Zurwehme, who was serving a life sentence for a 1974 murder, failed to return after day release last December and is suspected of killing four other people during his flight. A tourist was shot dead in June by police who thought they had cornered the fugitive.
