Okinawa police served a further arrest warrant Thursday on a detained civilian base worker for the rape and murder of a 20-year-old local woman in April, investigative sources said.
Kenneth Franklin Shinzato, 32, a former U.S. Marine who was a civilian employee of Kadena Air Base, was initially arrested May 19 on suspicion of dumping the woman's body.
Shinzato is suspected of raping the woman in a grassy field on a roadside in Uruma in central Okinawa and stabbing her to death with a knife on the night of April 28. The woman was taking a walk at the time.
