Nikita Bergenström

On 25 October 2022, he once again escaped from open prison in Kervo, by not returning from a visit to the doctor. He was arrested by the police the same day.

At the trial the two defendants blamed each other for the murders, but the court believed Routalammi's story. A psychiatric evaluation found both to be mentally competent for trial. However, the statement by a forensic psychiatrist found that Valjakkala suffered from a psychopathic personality and was very aggressive. Conviction for the murders was his 12th criminal conviction.

On 23 November 2011, he escaped from Kerava's parole prison. On 1 December he was found in Vallila, Helsinki. It is not believed that Fouganthine committed any crimes during his escape.

Valjakkala changed his name to Nikita Joakim Fouganthine in 2008 and later to Nikita Bergenström in 2013

Having served 19 years in prison, Fouganthine was due to be released on parole on 1 July 2008.

Fouganthine was released on 25 February 2008. He was arrested again on 12 April 2008 for breaking his release terms by, among other things, endangering the traffic, stealing a vehicle and driving a vehicle without a licence and driving an unlicensed taxi. Valjakkala admitted to the offences.

Fouganthine and his wife Alexandra married in May 2008.

In December 2008, the Supreme Court of Finland decided that he would be released with a suspended sentence in February 2009. Fouganthine was paroled again on February 2, and said he was writing an autobiography.

Just after midnight on 28 November 2006 Valjakkala escaped for the fourth time, this time from the labor prison in Hamina. He was captured on the evening of 30 November 2006 by police Readiness Unit Karhuryhmä in Maunula, Helsinki. Police assaulted the apartment which was suspected to be Valjakkala's hideout. Valjakkala was captured without resistance. After the incident Valjakkala went back to closed prison.

His next escape in 2004 from Sukeva prison lasted only 19 minutes and reached less than 1 km from the prison walls.

In 2002, he escaped from Pyhäselkä prison and traveled to Sweden with his wife, and was captured after a large police operation in Långträsk. Upon returning to prison after the 2002 escape he tried to commit suicide by hanging himself in his cell.

In April 1994, Valjakkala fled the Riihimäki Prison in Finland where he was being held. He took a teacher as a hostage, but he was apprehended nearby and the hostage escaped the situation unscathed.

In 1991, Swedish director Jan Troell directed a film based on the Åmsele murders, Il Capitano, starring Antti Reini.

Valjakkala was born in Pori. The series of events that led to the murders began when the 22-year-old was released from a prison in Turku on 1 May 1988, after which he started wandering through Sweden and Finland with his 21-year-old then-girlfriend Marita Routalammi.

Nikita Bergenström (formerly Juha Veikko Valjakkala, Aslak Valdemar Ahonen, and Nikita Joakim Fouganthine; born 13 June 1965) is a Finnish murderer convicted of the triple murder of a family in the northern Swedish community of Åmsele.
