Bruised Ego, Sibling Rivalry Behind Young Boxer Murdering Parents, Sister

Joint Police Commissioner, Southern Range, SK Jain said, "During questioning, we found contradictions in Arjun's statements. Eventually, he confessed that he killed them."

Rajesh Kumar (51), his wife Komal (46) and their daughter Kavita (23) were found dead at their home in Delhi's Neb Sarai on the morning of December 4 -- the couple's wedding anniversary. Their 20-year-old son Arjun made the first call to the police and told them of the chilling murders he discovered after returning from a walk. The probe that followed revealed a grisly tale of how bruised ego and sibling rivalry turned an aspiring boxer into a killer of his own family.

According to police, the crime scene did not suggest ransacking or theft. When police scanned CCTV footage of the area, they found no sign of a suspicious or forced entry either. The complainant, Arjun, told them no household items were missing. Therefore, robbery was ruled out. The police's investigation did not point to any dispute between the family and their neighbours. No angle of personal animosity was found either.

Police then turned to the son. "The version of son of the deceased was found suspicious as there were lots of contradictions in his statements," a police statement said. Initially, Arjun tried to mislead the investigation. But he broke down during the interrogation and confessed to the crime.
