A special Central Bureau of Investigation (CBI) court in Ghaziabad today pronounced Surendra Koli guilty of the murder of Nanda Devi in the 2006 Nithari serial killing case.
The quantum of punishment, however, will be pronounced on 7 October.
Earlier, the Supreme Court had sought the response of Koli on a plea of the Uttar Pradesh government against the Allahabad High Court's verdict that commuted his death penalty to life term.
Koli is the accused in the gruesome killings of Nanda Devi and Rimpa Halder.
Koli is also the accused in sexually assaulting girls before killing them, and allegedly eating them.
The case came to light when two Nithari residents hinted his involvement in the disappearance of several children over the last two years since 2004.
The case was further strengthened when carcasses of children were found in the drain outside the house of businessman Moninder Singh Pandher, where Koli worked as a domestic help.
On 13 February, 2009, Koli was sentenced to death by a special CBI court in Ghaziabad.
The high court had passed the order while allowing a PIL filed by People's Union for Democratic Rights, clubbed with another petition filed by Koli himself.
