At the time, there was an outcry across Nigeria, as many felt the sentence was too harsh.
The duo were subsequently transferred to the notorious Kirikiri maximum security prison in Lagos State where they were kept on death row.
In a statement on Tuesday, Governor Ademola Adeleke ordered that Olowukere be pardoned as it is important to protect the sanctity of life.
“I have instructed the commissioner of justice to initiate proceedings on granting the prerogative of mercy to the young man.
“Osun is a land of justice and fairness. We must ensure justice and protect the sanctity of life,” the governor wrote on X.
The fate of Maraquinho Sunday, who was convicted alongside Olawuker, is unclear as his name was not mentioned in the statement.
Over the years, Olowookere’s parents, human rights groups and other Nigerians have fought for his release.
His parents were recently on a podcast where they cried and begged for mercy on their only child.
It is expected to be released in early 2025.
Nigeria has not carried out executions since 2012, but currently has more than 3,400 people on death row.
