Air Force officials have identified an airman stabbed to death Friday outside the home of U.S. Forces Japan in western Tokyo, according to the Stars and Stripes website.

Master Sgt. Nicholas Vollweiler, 35, was stabbed with a knife at his home just outside Yokota’s east gate in the city of Tachikawa and taken to a hospital, where he was pronounced dead, multiple Japanese media reports said.

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

A woman identifying herself as Aria Saito, 27, an office worker from Tokyo’s Koto ward, was arrested at the scene on suspicion of attempted murder, a Tokyo Metropolitan Police spokesman said. Police were expected to upgrade the charge to murder.

Aria Saito, 27, was arrested at the scene of a fatal stabbing of an airman near Yokota Air Base, Japan, Friday.

“I stabbed a man I was dating with a knife, aiming at his right neck,” Saito told investigators, according to Japanese broadcaster TBS. She also said the incident happened after “break up talk got complicated.”

Col. Otis Jones, 374th Airlift Wing commander, called Vollweiler “a truly valued airman” who will be “dearly missed by our community.”

“His family, friends, fellow defenders, and all of the Yokota community are in our prayers during this heartbreaking time,” Jones said in the Air Force statement.

Vollweiler was a graduate of Pleasant Valley High School.

The Air Force will continue to work with Japanese police to investigate Vollweiler’s death, the Air Force statement said.
