A Japanese woman who was arrested on suspicion she killed an airman inside his home in western Tokyo last month has been indicted, Air Force officials report.

According to the Stars and Stripes website, 27-year-old Aria Saito of Tokyo was charged last week with murder and violation of the Swords and Firearms Control Law.

She is accused of stabbing Master Sgt. Nicholas Vollweiler, 35, on Nov. 9 inside his living room in the city of Tachikawa. Vollweiler, a 2001 graduate of Pleasant Valley High School, was taken to the hospital, where he was pronounced dead. The cause of death was determined to be hemorrhagic shock and suffocation from blood, according to prosecutors.

Vollweiler was assigned to the 374th Security Forces Squadron, according to an Air Force statement issued last month.

Saito, who is an office worker from Tokyo’s Koto ward, was arrested at the scene.

“I stabbed a man I was dating with a knife, aiming at his right neck,” Saito told investigators, according to Japanese broadcasts.

Prosecutors said Saito stabbed the right side of Vollweiler’s neck with an 8-inch knife held in her left hand with an intention of killing him.

She also said the incident happened after “breakup talk got complicated.”

Saito is also charged with illegal possession of the knife used in the stabbing as well as another 6.5-inch knife without a professional or justifiable reason, Stars and Stripes reported.
