OSAKA--Police found traces of blood in the bathroom of an apartment that was rented by an American tourist who has been linked to several body parts scattered in the Kansai area.

The room in Osaka’s Higashinari Ward showed no visible bloodstains. However, a closer forensics analysis detected the blood, investigative sources said.

The room, used for low-cost “minpaku” private lodging, was booked by Yevgeniy Vasilievich Bayraktar, 26, from New York, who met a woman from Sanda, Hyogo Prefecture, who has been missing since Feb. 16.

The 27-year-old woman was apparently one of several he had met through social networking services (SNS) and brought to the room, police said.

Bayraktar was arrested in Nara on Feb. 22 on suspicion of confining the Sanda woman in the room.

Two days later, police found a severed head in a suitcase in another room that Bayraktar had rented in Osaka’s Nishinari Ward.

Bayraktar also led police to a mountainous area of Shimamoto, Osaka Prefecture, and a forest in Kyoto’s Yamashina Ward where the torso, legs and arms of a woman were uncovered on Feb. 25.

Police plan to rearrest Bayraktar on suspicion of desecrating a body and abandoning a corpse.

Although the body parts have yet to be positively identified, police suspect they are from the missing woman, the sources said. Identification of the blood traces could determine if the body was dismembered in the room in Higashinari Ward.

According to the sources, the missing woman left her office in Sanda on Feb. 15 and told a friend she planned to meet an American she became acquainted with through an SNS site.

The woman met the suspect near JR Morinomiya Station in Osaka around midnight, and security camera footage showed them entering the Higashinari lodging together.

The camera also recorded a man believed to be Bayraktar carrying a large bag as he exited the building between Feb. 16 and 18. The footage never showed the woman leaving the place.

Around the same period, security cameras at train stations recorded a similar man carrying a large bag, which police suspect contained the severed body parts, the sources said.

After arriving in Japan in January, Bayraktar contacted various women through a “matchmaking” smartphone app and other means, according to the sources.

During his stay for about a week from Feb. 12 at the Higashinari lodging, security camera footage showed four or five women entering the premises with a man believed to be the suspect, the sources said.

All of those women were recorded leaving the building.

The app that Bayraktar used activates a GPS system that locates other app users nearby. App users can view the pictures and profiles of others on their smartphone screens. If two users sense a connection, they can start exchanging messages and arranging a meeting.

Such dating apps have been popular overseas, and they are now increasingly being used in Japan, mainly by young people.

Those apps can be linked to SNS such as Instagram and Facebook, allowing users to gain more information about other potential “matches.”
