Andrei Vladimirovich Sibiryakov (; February 28, 1964 – August 5, 1991), known as The Maniac from Lenenergo (, was a Soviet serial killer who killed 5 people in 1988. Biography Sibiryakov was born in Leningrad on February 28, 1964. At a minor age, he was first convicted of hooliganism, and after release he married.
