Moninder Singh Pandher, at whose house the killings took place, has been charged with conspiracy to murder, destruction of evidence and providing shelter to the accused.

Nithari villagers on Monday fought pitched battles with the police, both pelting stones at each other, outside the residence of a businessman who along with his servant allegedly sexually abused children and murdered them.
Security of Dasna jail, where Pandher and Koli are lodged, has been heightened.
The protestors broke the security barricades, pelted stones at the house and set on fire the effigies of Pandher and Surinder as a handful of Uttar Pradesh policemen looked on.
Tests revealed that the forensic examination of skeletal remains, including 16 complete and three incomplete skulls, suggested that four of them were of adult females, an equal number of male children and the remaining were of girl children.
The duo were produced before special CBI Judge Sapna Misra, who sent them to 14 days remand for the murder of Nanda Devi, Pandher's maid servant.
However, the documents attached with the report prepared by the then sub-inspector in-charge of the Nithari police post allegedly had glaring flaws, raising doubts about the police handling of the matter.
Ram Kishan, father of three-year-old victim Harsh, said he felt a sudden rush of uncontrollable anger when he sighted Moninder Singh Pandher, accused of killing 17 women and children along with his servant Surender Koli.
CBI sources said the polygraph test was necessitated after she continuously changed her statements.
For these unfortunate parents, the compensation being doled out by the state government is not enough. They want concrete information about their children.
Till now, police had not found any parts from the torsos of the 17 people killed at Nithari, giving rise to speculation that Pandher and Koli might have been involved in illegal organ trade.
