A Russian man, who murdered his date before raping and strangling the woman's 12-year-old daughter, has been identified through DNA analysis two years after the incident, police said on Tuesday.

The accused, identified as 35-year-old Aleksey Zhdanov, met the woman, 36-year-old Olga, at a grocery store in Nizhny Tagil, a town in Russia's Sverdlovsk region. The victim, who was a single mother, invited the man to her home for some drinks.

However, Zhdanov became aggressive and was asked to leave the home right away. Moments later, he allegedly picked up a knife and stabbed Olga multiple times, reported Yahoo Australia.

He then barged into the room of Olga's 12-year-old daughter. He raped the girl before strangling her to death with a cord.

"The suspect killed the woman by stabbing her multiple times in the neck and chest," an investigator said. "After that, he raped the child then strangled her to death with an iron power cord to get rid of a witness."

Their bodies were found the following day by Olga's mother who had arrived at the residence to celebrate the woman's birthday.

Police said on Tuesday that the 35-year-old accused was identified through DNA analysis and a criminal case has been launched against Zhdanov, who is currently in prison in connection with car theft, reported News.com.au.

He will face life imprisonment if found guilty of killing the mother and daughter.

In a similar incident in January, a man in the central Indian state of Madhya Pradesh raped his friend's teenage daughter before bludgeoning her with a rock and trying to bury her alive. The 14-year-old victim was found buried under bushes and was rushed to the hospital in an unconscious state with serious injuries.

The man, who used to visit the victim's home frequently, was taken into custody after an investigation. He was charged with rape and attempted murder after confessing to the crime. Meanwhile, the victim was reported to be in a stable condition at the time.
