William Quinn, the first American to be returned to Britain for trial under a 1986 Anglo-American extradition treaty, was convicted Tuesday of killing a London policeman 13 years ago and sentenced to life in prison. Quinn, 40, a San Francisco native, was convicted of shooting Constable Stephen Tibble, 21, on a London street in February, 1975, after being stopped by policemen investigating burglaries.
