In the fall of 2014, 13 hairs that could not be analyzed in Estonia were sent to Austria for additional testing. Austrian experts managed to identify in three of them mitochondrial DNA that did not belong to the victim and compared them with the DNA of the bearers of the male chromosome in Estonia. As a result of the work of experts the police were led to two men from the same family whose mitochondrial and Y-chromosomal DNA matched the profile of the sample found on the victim and the place where the body was found.
Police established that for one of the men it had not been possible to commit the crime and continued checking the second man. A DNA sample was taken from the man in February 2014. Three days later the man died in an apartment house in Tallinn after intentionally taking a drug overdose.
It has been established that the man was in the same area when the crime was committed. At the same time, the police have no information abut his activities at the time when the girl went missing and it may be possible that he had contact with the child earlier.
Because the man has died it is not possible to establish what he did on March 18, 2012 or gather data that would conclusively link him to the disappearance and killing of the child. It is also not possible at this point to additionally process samples taken from the victim and the place where the body was found to identify a unique DNA profile that would be sound enough evidence to link the man to the victim's death. Therefore the criminal procedure to investigate the death was ended on Monday. A reopening of the investigation is possible if it is necessitated by progress in scientific methods or additional information is received.
More than a hundred police personnel took part in the investigation during the four years. In addition to experts from Estonia top level Austrian, Dutch and German experts were involved in analyzing the samples taken from the victim's body and the place where the body was found. Leads were searched for using channels of the Europol, Interpol and the police of neighboring countries, and profilers from the UK and Russia were brought in. More than 2,100 people were questioned.
Proceedings that got their start as part of the investigation into the killing of Varvara have resulted in tens of sexual perpetrators being brought to justice in Estonia for altogether 121 alleged offenses during the four years.
The 9-year-old girl went missing near her Narva home on March 18, 2012. Numerous police personnel and tens of volunteers joined the search for the missing girl in the following days.
The girl's naked body was found on March 23 not far from the place where she was last seen alive, during a repeat check of the same location. Police had been unable to locate the body when going through the area for the first time because the body lay under a layer of snow.
