The Sheena Bora murder case is back in focus after the CBI’s special public prosecutor told the trial judge on Thursday that a set of remains examined by one forensic expert could not be traced. Police in Pen, Raigad, had found the alleged remains of Sheena Bora’s body in a forest in 2012. A site exhumation in 2015 had uncovered more bones and human parts, including teeth and hair.
