State of Maharashtra v. Santosh Kumar Singh is a high-profile case in India related to the rape and murder of a law student, Priyadarshini Mattoo, in 1996. The case went through several trials and appeals before a final verdict was reached in 2010.

The accused, Santosh Kumar Singh, was a senior official in the Indian Police Service at the time of the crime. The prosecution presented evidence that he had been obsessed with the victim and had raped and murdered her in a fit of rage after she rejected his advances.

After several trials and appeals, the case was finally heard by the Supreme Court of India in 2010. The court found the accused guilty of rape and murder and sentenced him to death.

This case is significant because it highlights the issue of violence against women in India and the need for a more efficient and effective criminal justice system to ensure justice for victims. It also highlights the importance of holding those in positions of power accountable for their actions, regardless of their social status or professional standing. The case also underscores the critical role of forensic evidence in criminal investigations and trials.
