Nielsen, who had lived in Switzerland since 1995, spotted the intruder, went outside and asked what he wanted. The neighbour pointed to Nielsen's front door, but instead of knocking, Kaloyev sat down in the garden. He waved a piece of paper with Nielsen's name on it. A neighbour spotted Kaloyev and asked what he wanted. On the afternoon of 24 February 2004, he set off for Nielsen's house. Kaloyev then hired a Moscow private investigator to find Nielsen's address outside Zürich, before travelling to the former air traffic controller's home in Kloten. At the memorial service for the first anniversary of the tragedy, he asked the head of Skyguide about the possibility of meeting the controller who had been responsible for the disaster, but received no response. Kaloyev spent the first year after the accident lingering at the graves of his family and building a shrine to them in his home. Svetlana's body landed in a corn field, while Konstantin's body hit the asphalt in front of an Überlingen bus shelter. He also found her body, which was intact, as some trees had broken her fall.
Vitaly Kaloyev participated in the search for the bodies and located a broken pearl necklace owned by his daughter, Diana. Yuri Kaloyev, the brother of Vitaly Kaloyev, reported that he suffered a nervous breakdown following the loss of his family. Vitaly Kaloyev had lost his wife Svetlana Kaloyeva ( Russian: Светлана Калоева) and two children, 10-year-old Konstantin ( Russian: Константин) and 4-year-old Diana ( Russian: Диана) in the Überlingen mid-air collision in 2002.

In 2004, Kaloyev travelled to the Swiss town of Kloten, where he killed Nielsen, who had since retired from air traffic work. Kaloyev held Peter Nielsen (16 August 1967 - 24 February 2004), the sole air traffic controller in Switzerland who was handling traffic the night of the collision, responsible.
