Sanjay Roy, the prime accused in the brutal rape and murder of a trainee woman doctor in Kolkata, has a history of violence against women and multiple failed marriages. He was a civic volunteer with the Kolkata Police and had access to several hospital departments. Roy’s mother-in-law alleged he was violent towards her daughter and concealed his previous marriages. He was also accused of running a hospital racket. West Bengal Chief Minister Mamata Banerjee has promised a CBI investigation if the police fail to solve the case by Sunday.
