Serhiy Tkach

Serhiy Fedorovich Tkach is a former Ukrainian police criminal investigator, originally from Russia, and a convicted serial killer who claimed to have killed 100 people. He suffocated girls aged between 8 and 18 and performed sexual acts on their bodies after they were dead. Although Tkach admitted his crimes and demanded the death penalty, after a one-year trial, a tribunal in Dnipropetrovsk sentenced him to life imprisonment for the rape and murder of 36 women and girls over more than two decades.
