Abe ‘outraged and speechless’ at latest in string of atrocities
Former US marine turned civil contractor Kenneth Shinzato was arrested on Thursday in connection with the disappearance of Rina Shimabukuro on April 28.
Ms Shimabukuro’s boyfriend told police she went for a walk that evening and never returned.
Mr Shinzato was arrested after police found the victim’s body at a forest location he gave them, but he had not yet been charged yesterday.
However, local media quoted sources close to the investigation saying he had admitted strangling and stabbing the victim.
“I feel extremely strong outrage,” Mr Abe told reporters.
“I have no words to express, considering how the family feels.
“We urge the US side to take thorough measures to prevent the recurrence of such events.”
Okinawa Governor Takeshi Onaga said he was “outraged” and that the death of the woman broke his heart.
“As I look back at all the developments to date, I’m simply speechless,” he said.
US ambassador Caroline Kennedy said: “We will double our efforts to make sure this will never happen again,” while the US State Department said the military was co-operating with police.
Two months ago a US Navy sailor admitted raping a woman at a hotel on Okinawa and US servicemen have committed numerous rapes and murders of Okinawan women and children since occupying the island towards end of World War II.
The island is home to more than half the 50,000 US troops remaining in Japan since the war.
The litany of outrages — compounded by the US military’s insistence on trying suspects by court martial rather than in Japanese civilian courts — has fuelled strong opposition to the US military presence.
Mr Onaga has been among those leading mass protests against the planned relocation of US Marine Air Station Futenma from its present unsafe location in a suburb of the capital to a more remote spot, demanding instead that it be closed altogether.
