Ghaziabad: Surendra Koli, awarded death penalty in all the five cases decided earlier related to the Nithari killings, was on Wednesday held guilty of abduction, murder, rape and destroying evidence in the sixth case.
CBI judge Pawan Tiwari held him guilty in the case relating to a 25-year-old domestic help at the house of Koli's employer Moninder Singh Pandher before she disappeared on 31 October, 2006.
The quantum of punishment will be pronounced on 7 October.
Special public prosecutor (CBI) Jai Prakash Sharma said the CBI judge found Koli guilty of abduction, murder and rape of the woman and destroying evidence.
The Nithari case came to light in 2006 when police discovered skulls and bones of 19 people from near Pandher's house in the Noida village.
The case was handed over to CBI for the probe.
A total of 19 cases were lodged and CBI filed closure reports in three of them due to lack of evidence.
Sixteen cases were filed against Koli, of which court had awarded death sentence in five.
