An African-American boy, George Stinney Jr., who was executed at age 14 in the killing of two young White girls has been exonerated in South Carolina, 70 years after he became the youngest person executed in the U.S. in the 1900s. A judge ruled he was denied due process.

"I think it's long overdue," Stinney's sister, Katherine Stinney Robinson, 80, tells local newspaper The Manning Times. "I'm just thrilled because it's overdue."

In her ruling, Circuit Judge Carmen Mullen wrote that she found that "fundamental, Constitutional violations of due process exist in the 1944 prosecution of George Stinney, Jr., and hereby vacates the judgment."
