On International Happiness Day we bring you terrible tales from Russia and round off the episode with vodka.

Jonatan covers the Academy Maniacs, a teenage duo who murdered and attacked residents in Akademgorodok of Irkutsk. Ana covers the Maniac of Novosibirsk who went on an 8 year killing spree only for DNA to solve the case in recent years.
