The 20-year-old woman accused in the Pune fort murder case dialled her lover and co-accused about half an hour before she allegedly pushed her fiance off a cliff, police have found. Siya Goyal allegedly had a 'secret call' with Chetan Chaudhary just 34 minutes before the murder, sources said, citing their call details record (CDR), which is now being seen as their final go-ahead for the chilling murder plot to eliminate her fiance Ketan Agarwal, 25. The revelation followed an in-depth forensic examination of the mobile handsets of Goyal and Chaudhary, sources said. The last call between her and Chaudhary is being treated as the most significant digital evidence of a conspiracy, uncovered by the technical surveillance team of the Pune Rural Police in the sensational murder probe.
