A family found dead at home
On 31 July 1990, police entered a detached house in the village of Vols in Kirkkonummi after Veikko Rytkönen failed to appear at work and could not be reached. Inside, investigators found Rytkönen, his partner Berit Andersson and their three-month-old daughter Jessica dead.
Yle's later reconstruction placed the likely time of the killings between Saturday evening and Sunday morning, giving the offender a significant head start before the family was discovered. Police found no conventional signs of a forced break-in.
What investigators established
The investigation indicated that the assailant went to the bedroom and killed the adults. Water from a damaged waterbed and heavy rain outside complicated the preservation of possible evidence. Authorities also concluded that money and personal items were missing from the house.
Earlier reporting noted that the household had received nuisance telephone calls, but investigators later considered it unlikely that those calls were connected to the murders. Police have withheld some details about the weapons and crime-scene evidence for investigative reasons.
Suspicions without a proven offender
Over the years, investigators have examined several people and theories. A close relative of Rytkönen was detained for a period during the investigation, but the evidence did not establish that person's guilt. No one has been convicted of the murders.
Because murder does not expire under Finnish law, the National Bureau of Investigation can continue examining new information. Yle reported in 2024 that the case remained open and that police still regarded it as an active unresolved triple homicide.
Why the case endures
The Kirkkonummi case is exceptional in Finnish criminal history because three members of one household were killed and the identity of the offender remains unknown decades later. The passage of time has also made the distinction between verified evidence and speculation especially important.
For that reason, this archive records only the findings publicly attributed to investigators and reliable reporting. The existence of past suspects or investigative theories should not be read as proof that any identified person committed the crime.
