It sounds like it was the bomber, Serhiy Batryn, that was reported as dead. Conflicting reports as to whether he has actually died. This was not related to Russia from what I could gather. He had a long standing feud with members of the local council.
Yeah, this is why I don’t agree with capital punishment. Sure, many victim’s families will want the perp to die. That doesn’t mean we as a society have to be a place where we grant the wishes of blood lust. It doesn’t make the world a better place, just a bloodier place.
