India- A suspect in the gruesome murders of 17 people, mostly children, near the Indian capital has told investigators he had sex with the dead bodies and ate their organs, a report has said.

The Times of India said Surender Koli admitted to carrying out the crimes alone and that his employer, businessman Moninder Singh Pandher who has also been arrested and charged, was unaware of the killing spree.

The grisly revelations emerged after the two accused were subjected to “narco-analysis” — including truth drugs, polygraph tests and brain mapping — at a national forensic laboratory.

Results of the tests are not admissable as evidence in court, but are designed to help police with their investigation.

The two were arrested on December 29 from New Delhi’s affluent Noida suburb after an overwhelming stench led to the discovery of carefully chopped-up body parts in a drain next to Pandher’s home.

But Pandher was apparently unaware that his servant used sweets and chocolates to lure the victims to the house, before killing them and raping their bodies, the Times of India said.

Koli, who previously worked as a cook in a hotel, narrated how and when he killed his 17 victims with precision. He also remembered the names of 15 victims, the newspaper said, quoting unnamed investigators involved in the tests.

“Sahab (master) did not know,” Koli was quoted as telling investigators, adding the murders were committed when Pandher was away.

Asked what he had done with the missing torsos of the victims, Koli disclosed that he ate some of the organs and cut up others and flushed them down the toilet. The dismembered parts were disposed of separately.

Koli said his first victim was a four-year-old girl. He admitted to trying eating the child’s liver, but said he vomited immediately.

His co-accused, meanwhile, emerged from the tests as a womaniser who used Koli as a pimp to find him prostitutes.

Pandher’s family says reports of the results of the narco-analysis test were a relief.

“I had always thought Surendra (Koli, the servant) was behind all this. My father used to be out of town for long periods on business,” Pandher’s 23-year-old son, Karan, told the newspaper.
