The US Supreme Court will hear the case of Richard Glossip, a death row inmate from Oklahoma.

Glossip has maintained his innocence since his 1998 conviction in a murder-for-hire case.

Two independent investigations have brought up issues with the evidence against Glossip, including witness lies and destroyed evidence.

Prominent figures such as Susan Sarandon and Sister Helen Prejean have expressed support for Glossip.

The state's attorney general believes Glossip did not get a fair trial and advocates for a new one.

Oklahoma's Republican Attorney General now supports sparing Glossip's life.

The Supreme Court's decision in this case could significantly impact the criminal justice system.

Justice Neil Gorsuch will not be involved in the case.
