The sight of two young girls hanging from a tree in Uttar Pradesh's Badaun in May horrified India and drew reactions from across the world. Five months on, the Central Bureau of Investigation says they were not gang-raped and murdered as the police said, but they hanged themselves.
The CBI said "40 scientific reports" have confirmed suicide, but the families of the girls - who were cousins - have rejected it. They say they want Prime Minister Narendra Modi to ensure a fair probe.
"If we don't get justice we will kill ourselves," said Sohan Lal, the father of one of the girls.
The girls, who were 14 and 15, were found hanging from a mango tree near their village on May 28, a day after they were reported missing. Based on their autopsy, the police said the girls were raped, beaten and hanged alive.
The CBI, which took over the investigation in June amid global outrage, said the autopsy that confirmed rape was unreliable. It also said a key witness had lied about seeing the girls dragged by some men.
Investigators are convinced the cousins committed suicide, possibly because of "societal pressure" in a case that involved an affair between the older girl and a villager.
To test the theory, the CBI conducted dummy tests at the site. They also noted that there were no signs of struggle.
The girls' families had alleged that they were kidnapped and murdered by five young men of a family in the village.
In August, the agency said the girls were not sexually assaulted, citing forensic tests and a medical board's assessment. Five men arrested in the case, including two constables, were let off on bail after the CBI refused to file a charge-sheet against them.
The CBI's findings have raised a political storm.
"The CBI hasn't gone completely into the facts. We will investigate," said Uttar Pradesh politician Mayawati, who had targeted the state's ruling Samajwadi Party for failing to protect women.
The Samajwadi Party says those who targeted their government must apologise. "We were maligned. Media has been proved wrong," said Uttar Pradesh Chief Minister Akhilesh Yadav.
