Federal investigators in India have brought charges against two men for their alleged role in the sexual assault and killing of at least 19 children and women, authorities have said.
Moninder Singh Pandher, a prosperous businessman, and his servant, Surender Koli are the two men accused in the case that shocked India.
News of the killings first emerged in late December after skeletons were found in a Delhi suburb.
Relatives of the victims said police had ignored their complaints as up to 38 people went missing over two years.
The Central Bureau of Investigation has charged Pandher only with destruction of evidence. Koli has been charged with murder, rape and necrophilia.
The CBI said the prosperous businessman had tried to help Koli because he took good care of him.
"Pandher was unaware of the heinous acts of Surender," Arun Kumar, CBI joint director, said.
Virtually putting the blame on Koli for the murders, the CBI said he had carried out the crimes while his employer was away from his home in Noida in the outskirts of New Delhi.
