Moscow, Russia - Moscow priest Daniil Sysoyev most likely has been killed for his missionary activity among the non-Orthodox Russian population, a source at law enforcement agencies told Interfax.
"He had recently received constant death threats from some extremist organizations. Daniil Sysoyev complained about it several times to the Federal Security Service," the source said.
Fr. Daniil said he received anonymous phone calls and e-mails promising to "have his guts for garters," he said.
"Sysoyev received the last threat in early October. Someone called him and said he had been sentenced to a death penalty," the source said.
Rev. Daniil is known as an experienced theologian who had been in constant dispute with the extremist branches of Islam. He began receiving threats four years ago after holding a public debate with Vyacheslav Polosin, the former Orthodox priest who converted to Islam.
Fr. Daniil might also have been killed by members from the so-called sect of Rodnovers (Slavic Neo-pagans), the source told Interfax.
Investigators are following all lines of inquiry but this theory remains the main one, he said.
This is evidenced by the fact that the perpetrator did not leave the weapon at the crime scene, he said. "Rodnovers are not professional killers, which is why they count every barrel," he said.
The Rodnovers organization mainly consists of young pagans.
Earlier Rodnovers staged an explosion at one of Moscow's churches.
