Offender’s DNA matches that of wanted serial rapist who turns out to be his father
Having checked the detainee’s genotype against the base, the police found it was similar to that which had been taken at the rape scenes.
Tomsk investigators were able to get on the trail of a suspect in a series of rapes thanks to the DNA profile of his son.
According to RIA Novosti, the young man was taken to the police for an offense not related to the "Tomsk rapist" case. However, having checked the detainee’s genotype against the base, the police found it was similar to that which had been taken at the rape scenes. When the offender’s father was made to take the test, too, it was clear that he was the one the investigators had sought for years.
The crimes were committed in the town of Strezhevoy between 2004 and 2017. They remained unsolved until the suspect, a 60-year-old local man, was finally detained.
“Over the course of three years, more than seven thousand people were genotyped in the town of Strezhevoy,” said Dmitry Rogovich, the Tomsk region head of the forensic department of the Investigative Committee. “At first, they were ex-cons, mentally ill, rotational workers, Strezhevoy residents living around the area where the crimes happened. Later, continuous genotyping of all persons who were brought in to Strezhevoy police stations was organized. That gigantic work finally yielded fruit.”
For two years, the investigators checked the genotypes of the suspects in various criminal cases, and ended up checking the families of the detainees for involvement in the rapes. It took another year to finally find the match.
The son of the alleged rapist was only seven years old in 2004, when the first crime was committed.
Only one of the five victims managed to make out the rapist’s facial features, after which a composite portrait was made. The crimes were committed at night, usually in August or September. The man generally attacked his victim from behind, pulled her hat over the head and assaulted her threatening with a knife. After that, he left towards the same street. It was not until 2016 that the cases were combined into a series of crimes.
