MOSCOW, February 3 (RIA Novosti) - Moscow Region police have arrested a woman suspected of seeking out her "doppelgangers" on a popular social networking website and then killing them for their property, Russian media said on Tuesday.

The woman, 46-year-old Yuliya Pechenyeva, made the acquaintance of and killed at least three single women whose appearance was strikingly similar to her own, the life.ru news website reported. The "two-legged predator" is said to have met the women on Russia's odnoklassniki.ru.

After killing the women, Pechenyeva stole their documents, and then applied for and received bank loans in their names.

Her "career" in the real-estate business came to an end after she sold a flat to a young couple in the Moscow Region town of Odintsovo and the new tenants moved in before she had had a chance to dispose of the remains of the owner. The couple subsequently discovered the decomposing body parts of Svetlana Sokolova on the balcony.

"That was a real mystery," a police source told the paper. "We determined that the victim was the owner of the flat. However, the new residents were absolutely sure that she was the smiling and kind woman they had literally just bought the flat from!"

Police eventually located and arrested Pechenyeva after discovering that she was already on the federal wanted list for two similar murders in Russia's second largest city of St. Petersburg.

Investigators say the cold-blooded killer would do everything possible to strike up a friendship with her future victims, even buying a dog of the same breed as the one owned by Sokolova.
