Antti Veikko Ilmari Siltavuori (October 29, 1926 – March 9, 2012), better known as Jammu Siltavuori or Jammu-setä ("Uncle Jammu"), was a Finnish murderer and sexual offender.

Early life

Veikko Siltavuori was born in Vaasa, Finland. Information about his early life is very limited. According to some sources his childhood was very hard and complicated, because of his alcoholic father who beat Veikko very much. He was bullied in school and he was called a weasel because of his dirty clothing.


Siltavuori became well known in Finland when he murdered two eight-year-old girls, Päivi-Maria Hopiavuori and Tanja Johanna Pirinen in 1989. He burned the bodies shortly after. He had picked up both girls into his car from Myllypuro, a neighbourhood in Helsinki, on March 3, 1989. Prior to this, he had been convicted of raping a five-year-old girl, sexual harassment, and attempted murder. He was convicted to life imprisonment already in the 1950s or 1960s but he was later paroled. He had also built a self-made jail complete with cells, barred windows and small toilets in Paltamo, Kainuu, but there is no evidence that he built it for keeping the children hostage.


For the two murders in 1989, Veikko Siltavuori was sentenced to 15 years in prison with the possibility of parole after 10 years, because a mental health examination legally found him to be partially insane. If that had not been the case, Siltavuori would have been again sentenced to life imprisonment.

After 10 years elapsed, his first and second parole hearings in a Prison Court were unsuccessful. After he served one more year in jail, the Prison Court released him on strictly supervised parole on January 31, 2000, on his third parole hearing. However, he was immediately involuntary committed to the Niuvanniemi mental hospital in Kuopio for criminal-psychiatric reasons. The involuntary commitment was reaffirmed in 2007 by the administrative court of Kuopio, on the basis that if he was released, he would be a serious security risk.


In Niuvanniemi, there was an attack on Siltavuori, which injured him such that he spent his final years in a wheelchair. He reportedly died in March 2012 at the age of 85 in Kuopio. He was severely demented.[1]
