While 21 states have moved to ban life without parole for juveniles, all legislative efforts to do so in Oklahoma have failed.

TPD Sgt. Shane Tuell confirmed on Wednesday the investigation is ongoing, but said he did not know who or what was being investigated.

“I should have gone to prison,” Dana Barker said. “I did something horrible, but I don’t know that I should have given up the rest of my life.”

The courts say dozens of Oklahoma prisoners serving life without parole for crimes they committed as teenagers have the right to new sentences, but many are still waiting for a second chance.

Many Oklahomans serving life without parole for crimes committed as juveniles have struggled to get their cases reopened for a new sentencing hearing or even to get the courts to appoint them an attorney.
