An alleged serial killer who practiced cannibalism has been arrested in Central Russia. The detainee has confessed to at least six murders, but the number of victims could be higher.

­Twenty-four-year-old Aleksandr Bychkov was initially arrested in Russia’s Penza Region on suspicion of involvement in a hardware store robbery. However, while being questioned Bychkov suddenly began telling police about corpses he had buried in a ravine near his home.

According to the police spokesperson, investigators found the remains of six people. They were “recovered from the ground and sent for examination.”

The examination revealed that Bychkov had chopped his victims into pieces. He then cut out their livers and ate them.
