Brampton hammer murder 1992/ Runo Mark Cairenius
Runo Mark Cairenius moved to Canada with his spouse, Airi Anneli Mäkinen, in 1972. Cairenius, a finnish architect/inventor, had previously worked as the city architect for the municipality of Tuusula in Finland. He had also received government funding for his inventions. They had two sons, one from Airis previous relationship.In 1990, Airi applied for a divorce, and got a restraining order due to Mark's domestic violence. Mark was kicked out from the family's home. This caused Mark to begin stalking her. This escalated into Mark sawing off the roof of her house, and winching it onto the backyard, causing damages totaling over 50 000.
In 1991, Mark wrote a book, describing all the ways Airi had supposedly lied to the government about him, and accusing her of sexual deviancy, among other things. The last 2 chapters of the book were left empty. He sent copies of the book to media, the government, friends and family.
In 1992, he wrote the last 2 chapters. It described how he was going to murder Airi, because it was the only option he had. He took the copies to the post office, and murdered Airi on broad daylight in public with a hammer, on the sidewalk outside her house. The couples 10 year old son witnessed the act. A neighbor called the police, and went outside to talk with Mark. He asked Mark "What are you going to do now?" His response was:"About 25 years."
The finished copies of the book found their way to the recipients after the murder had already taken place. In the book he describes why the murder weapon has to be a hammer:
"So it has to be a hammer, the same tool she used to convince the court that I'm weird and violent. With a hammer I had built a house for us, a home for her son from a previous marriage, Timo, until he was 19, a home for her and our sons - and to me aswell. It's a damn good tool."
During the investigation, the police came to the conclusion that he was in a delusional state, and had a self-inflicted victimhood mentality, and saw no other options in his situation but to commit a murder. He was sentenced to life in prison in the Ontario court.
Cairenius has been in prison since 1993, he was first eligible for parole in Canada after serving 25 years. He has on numerous occasions asked to be transfered to Finland, but the finnish government has denied these requests, for reasons that aren't entirely clear. As he is a finnish citizen, these requests are typically accepted. If he had been transfered to Finland, he wouldve been out of prison possibly even 20 years ago.
He has consistently refused to undergo psychiatric evaluations, or take part in any reprogramming courses. This has made him ineligible for parole in Canada, even if otherwise he would've been eligible close to 10 years ago. His latest parole request was denied in 2026. He is still refusing to co-operate with any prison programs, or accept responsibility for the crime. He is now 86 years old.
In 2002, he was found unconscious in his cell, with "1 tooth" written on his forehead.
The original prosecutor of the case, Steve Sherriff, plead with the parole board later to release Cairenius. He said that "Cairenius has already paid an awesome price for the crime, an awesome price he deserved. It was a crime of passion, and the likelihood of him committing further homicides is 0."
