Bio

Antti Veikko Ilmari Siltavuori was born on October 29, 1926, in Joensuu, Finland. He grew up in a different era, during which Finland was going through many changes. There is limited information about his early childhood and family life.

As a young person, Siltavuori faced challenges that would shape his later life. He had difficulties with mental health and was considered to have intellectual disabilities. These struggles affected his education and his ability to connect with others.

During his youth, he moved to the town of Paltamo. In this place, he built a self-made jail complete with cells and barred windows, though it is unclear if it was intended for any malicious purpose. This detail reflects his unusual behavior at a young age.

As he grew older, he faced legal issues. Siltavuori was convicted of multiple offenses, including serious crimes against children. These convictions started to form a pattern that followed him throughout his life.

By the late 1980s, Siltavuori's actions would lead to significant news in Finland. His early life was marked by behaviors and incidents that suggested deeper problems. However, the full impact of his life continued to unfold in ways that shocked the community. He later became known as "Jammu-setä," or "Uncle Jammu."

Murder Story

Antti Veikko Ilmari Siltavuori, known as "Uncle Jammu," murdered two young girls, Päivi-Maria Hopiavuori and Tanja Johanna Pirinen, on March 3, 1989. He picked up both girls for a car ride in Helsinki, Finland. After the crime, he burned their bodies.

Siltavuori had a history of violent behavior before these murders. He had been convicted of raping a five-year-old girl, sexual harassment, and attempted murder in the past. Due to his mental health issues, he was found partially insane. This affected his sentencing for the murders.

On December 14, 1989, he was sentenced to 15 years in prison. He was eligible for parole after serving 10 years. However, his first two parole hearings were unsuccessful. He served 11 years in prison before finally being granted supervised parole on January 31, 2000, during his third hearing.

Despite being released on parole, he was immediately committed to the Niuvanniemi mental hospital in Kuopio. The court determined that his release would pose a serious risk to public safety. In the hospital, he was attacked and became unable to walk, requiring the use of a wheelchair.

Siltavuori died on March 9, 2012, while still in the mental hospital. His crimes and the impact they had on society are still remembered in Finland.
