The Crime and Punishment by Fyodor Dostoevsky

Ryan international school student arrested in Pradyuman murder case. Two months after the CBI took over the investigation there is a new revelation made on the news early in the morning. The friends that saw ex inside the examination center that morning claim he wrote absolutely nothing on his paper. He later told his friends that he had left the paper blank because his hands were shaking the entire time and he couldn't even write a word. This means that either Ashok Kumar in prison for more than two months now is completely innocent or that the CBI washed the investigation up when they arrested a school student for the murder.
