The U.S. Supreme Court will not consider the constitutionality of a 241-year prison sentence given to a St. Louis man more than two decades ago.

The high court on Monday announced it would not hear the case of Bobby Bostic. The justices gave no reason for their decision.

Bobby Bostic was 16 when he committed several felonies in the course of an armed robbery. Two years later, he was sentenced to 241 years in prison.

Advocates for juvenile sentencing reform say that runs contrary to earlier U.S. Supreme Court decisions limiting how harshly the courts can punish young defendants who have not killed anyone, and they are now asking the justices to weigh in.
