Antti Veikko Ilmari Siltavuori (born 1927), also known as Jammu-setä ("Uncle Jammu"), is a man from Finland who murdered and burnt two 8-year-old girls called Päivi-Maria Hopiavuori and Tanja Johanna Pirinen, that he had picked for a car ride from this neighborhood march 3rd 1989.

He had been earlier convicted for raping a five year old girl, sexual harrasment and attempted murders.

He originally received a 15 years sentence for his crimes as he was found mentally retarded. If that had not been the case, he would have been sentenced to life imprisonment. The Finnish Supreme Court, however, found later some additional mitigating factors and ruled a life sentence to be overall inappropriate in his case.

The reviewed sentence was the usual determinate sentence of 15 years with parole possibility after 10 years. 10 years passed and his first and second parole hearings in the Finnish Prison Court (similar to Parole boards in the U.S.) were unsuccessful.

After serving 11 years, on the third parole hearing the Prison Court finally let him out on strictly supervised parole, but he nevertheless has spent the last few years in Niuvanniemi mental hospital (in Kuopio) for criminal-psychiatric reasons.

Jouko Turkka's novel Häpeä ("Shame") tells something about that. Says Turkka: "Jammu Siltavuori is the most hated man in Finland. No presidential candidate would want to have his vote. The candidate would pay money if Jammu would publicly announce that he would vote some other candidate. Church or any other religious organization would reject him even if the God itself would indicate that Jammu's sins are forgiven. Nobody wants anything from him, no money, no apologies, no begs for forgiveness. He is the most important issue in cultural life of Finland. Anyone who would express any kind of mercy would undersign his own death penalty."

Antti Veikko Ilmari Siltavuori (born October 29, 1926 in Joensuu, Finland) (also known as Jammu Siltavuori or Jammu-setä, "Uncle Jammu") is a Finnish man who murdered two 8-year-old girls, Päivi-Maria Hopiavuori and Tanja Johanna Pirinen. He burned the bodies shortly after. He had picked up both girls for a car ride 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, 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 had 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 cannot walk and has to stay in the wheelchair. It is unlikely that he'd be released.
