Anonymous telephone callers, saying they represented an Arab group, which they did not identify, claimed responsibility for the killing of Kenneth Marston,43, but police said they are still not certain that the act was a reprisal for last week's American bombing raid on Libya or, in fact, if it was connected in any way to the problems of the Mideast.
Meanwhile, in the Marston killing, police were looking into two other possibilities in addition to a Mideast link. Investigators were checking whether the killing was related to the arrest in March of a reputed organized crime figure accused of receiving part of nearly $1 million in goods stolen from Black & Decker eight months earlier.
In another incident for which no group claimed responsibility, West German police said Friday that a Canadian military van and the private car of a U.S. serviceman were damaged in arson attacks near Heidelberg, in central West Germany. Police said both incidents occurred Thursday in the town of Leimen-St. Ilgen-Geiberg, about three miles southwest of Heidelberg.
