The minor son of 35-year-old Rakhi Bhadra who was brought to the capital to give a go-ahead for his mother's post-mortem examination has gone 'missing', the police said.
According to the police, the 17-year-old had gone for dinner with his friend on Thursday before he simply disappeared. His phone is also switched off, leaving the police with no other option but to proceed with the post-mortem examination after presenting the 17-year-old help - the main witness in the case - to identify Rakhi's body.
Investigators on Friday said they were in the process of accessing one of the most crucial documents in the murder case - the school leaving certificate of the minor servant.
Officials said a team was questioning the parents of the minor help at his home in Varanasi and had sought his leaving certificate from a local school where he studied till class five.
Meanwhile, sources said Jagriti Singh, the main accused, had had a bitter confrontation with her MP husband at the Chanakyapuri police station - where both of them are lodged - on Thursday evening.
A post-mortem examination conducted on Rakhi on Friday evening, according to police sources, revealed 32 distinct injury marks on her body.
"In her statement to the magistrate, Meena, who is currently under treatment at RML hospital, has claimed that another reason for Jagriti's animosity towards her was the suspicion that she was having an affair with the MP," said a senior officer.
