It was a crime that thundered across Kansas City, took the lives of six firefighters, and 28 years later, still resonates as a shattering, life-changing moment for countless people. And on Wednesday, many of those people packed a Kansas City courtroom — and an overflow room with a monitor — for a hearing to determine if Bryan Sheppard, one of those convicted of that crime, will one day walk out of prison. The U.S. Supreme Court granted Sheppard that chance after ruling it is unconstitutional to sentence juveniles to a mandatory sentence of life in prison without first taking into account individual factors in their lives.
