The teen's liver and lungs were ruptured and an object was stuffed inside her privates, according to doctors.
While the Haryana Police authorities have constituted two SIP probes to look into this case, the girl's father, a tailor, who had complained about his missing daughter on January 10 had reportedly alleged that the Police did not take the case seriously which resulted in the death of his daughter. Her mutilated body was found in a village in Jind district on Friday and was sent to PGIMS for the post-mortem.
The 11-year-old Dalit girl's dead body was recovered from a nearby stagnant pond on Sunday evening.
It said the girl's body was found with 19 severe injuries and signs of "unspeakable torture". They also switched off her cell phone, the victim said in her complaint to the police.
The girl had allegedly tried to escape from her assaulters as the doctors said that there were clear signs of defence.
The 15-year-old had left home for her tuition classes last Tuesday. The officials have also formed a Special Investigation Team and four other squads to find the accused.
Later, they burnt her clothes to destroy the evidence before dumping her body. "We have asked the police to provide us the scene of the crime report and photographs of the spot for confirmations", Dr SK Dattarwal added.
"My daughter was killed brutally, I want justice for her. If the administration had done its job well, an incident like this would have never happened", father of the victim said. He said the police interrogated the two men as they suspected they were involved in the assault.
Meanwhile, Haryana Chief Minister Manohar Lal Khattar assured the culprit in the case would be nabbed soon. The accused later committed necrophilia after murdering the girl.
She had reportedly been abducted by a 20 year old man, who is missing from his village and has already been booked by the police.
The assaults on women and girls - and mutilation of their private parts, in some cases - remind of the brutal gang rape and murder of a physiotherapy student in Delhi in December 2016 that led to a huge uproar across the country.
