Surendra Koli, who was acquitted in the last remaining Nithari killings case in 2025, died by suicide in Haridwar on September 18, 2026, according to police. Koli had spent nearly 19 years in prison after being accused in the infamous 2006 Nithari killings in Noida. He was accused of abducting, sexually assaulting and murdering women and children, with human remains later recovered from drains near a bungalow in Nithari. Koli worked as domestic help for businessman Moninder Singh Pandher, and police filed multiple cases against the two in connection with the killings. Koli was convicted in several cases and sentenced to death, but those convictions were subsequently overturned. In 2023, the Allahabad High Court acquitted him in 12 cases, with the Supreme Court later upholding those acquittals. In November 2025, the Supreme Court acquitted Koli in the final case against him, involving the rape and murder of a teenage girl, clearing the way for his release from prison. At the time of his death, Koli had been acquitted in all the Nithari-related cases against him. The Nithari killings remain one of the most closely followed criminal cases in India, nearly two decades after they first came to light.
