Just hours before the murder, Walkar had texted her friend on Instagram that she had some news to share with him. The man reverted two hours later but never received a reply.
Aaftab told the police that he used to chat with Walkar's friends in order to mislead them. He called a common friend and asked him about Shraddha's whereabouts -- this was months after he killed Walkar.
Shraddha's family hadn't been in touch with her because of which her murder remained under wraps for nearly six months.
Aaftab had also entered into another relationship with a doctor and allegedly brought her home.
He also gave her Shraddha Walkar's ring.
The police are also exploring this angle.
Poonawala was working at a Gurgaon call centre at the time of the murder and was sacked by the management over bad behaviour with women employees.
The police had to work hard to find the remnants of Walkar's body.
Poonawala had thrown the parts into several places across Delhi and NCR.
