Oklahoma City police officers have begun erecting barricades around the governor’s mansion, the Black Times reported, as governor Kevin Stitt considers stopping the impending execution of controversial Oklahoma death row inmate Julius Jones.

The state parole board has twice recommended that Jones, sentenced to execution for the 1999 murder of Paul Howell, be removed from death row, citing doubts about his true guilt. The decision, however, ultimately rests with Governor Stitt, and the execution will take place on 18 November unless he elects to grant Jones clemency.

The Independent has contacted the Oklahoma City Police Department and the governor’s office for comment.

Family members and activists supporting Jones have been camped out around the clock at the state capital, praying, chanting, and hoping to meeting with governor Stitt as he considers whether to allow the execution to go forward. So far, however, the governor hasn’t directly addressed the group or spoken with Jones’s family, though faith leaders supporting Jones have met with governor’s office officials.

Instead, the governor is reportedly in “solitude praying.”

A passionate innocence movement has sprung up around Jones’s case in recent years, and high-profile backers of the “Justice for Julius” campaign rallied to his defense as his execution date grows closer, including actor Mandy Patinkin and reality star Kim Kardashian, who has visited Jones in prison.

“This is the cold machinery of the death penalty,” she wrote on Twitter on Tuesday, “an innocent man could be put to death. My heart breaks for Julius and so many others who have suffered from such tragic miscarriage of justice.”
