At 9, Aug. 18 -- A chilling WhatsApp message, desperate calls to her parents and CCTV footage from her Bhopal home form the centrepiece of the CBI's reconstruction of the final hours of 34-year-old Twisha Sharma.

36 pm on May 12, Twisha allegedly sent a message to her sister-in-law Rashi Abrol: "Ask him to collect leftover of his wife. But tomorrow. Let me die in peace right now."

Four minutes later, CCTV footage cited by the Central Bureau of Investigation (CBI) allegedly showed Twisha walking alone from the ground floor of her Bhopal home towards the terrace.

She spoke to her mother again around 10:05 pm. The call later disconnected.

The details are part of the CBI's 30-page chargesheet filed on August 14 against Samarth and Giribal...
