The Geeta and Sanjay Chopra kidnapping case (also known as the Ranga-Billa case) was a kidnapping and murder crime in New Delhi in 1978. It involved the kidnapping and subsequent murder of siblings Geeta and Sanjay by Kuljeet Singh (alias Ranga Khus) and Jasbir Singh (alias Billa). Although the children were kidnapped for ransom, they were killed after the kidnappers learned that their father was a naval officer, on the assumption that he was not wealthy. Both men initially admitted to raping Geeta before her murder. They later retracted their statements, and forensic evidence could not confirm the rape. Upon circumstantial evidence including evidence that Geeta had been stripped naked, it was later confirmed beyond reasonable doubt that rape was committed. The two kidnappers were convicted and sentenced to death. The execution was carried out in 1982.
