Local media in Saint Petersburg reported that university professor Oleg Sokolov was drunk and fell into the river as he tried to dispose of body parts. Police reportedly then went to Sokolov's home where they discovered the decapitated body of Anastasia Yeshchenko, 24, with whom he had co-authored a number of works. (Photo by PETRAS MALUKAS / AFP)
