As the new nation struggles to build a police force and judiciary following decades of civil war, rights groups are appealing for it to abolish the death penalty.
Mother-of-five Mary Sezerina, 45, admits her crime. But, like many others, she says she was not allowed to defend herself after she killed a relative seven years ago. She told IRIN her story:
"I am here because there is a problem: I killed a person, and that's why I'm here.
"The police brought me to the police station for two days, and then they brought me here.
"I killed my sister-in-law because she was coming to my house stealing things and running away. When she came back one day and stole, I took an axe and killed her.
"There was not any lawyer to defend me. Then my husband died, so I didn't have the money to repair what I did, so I'm in here. (Customary South Sudan law allows perpetrators to give cows to the victim’s family in lieu of a jail sentence.)
"I am condemned to death, but they didn't say when. They never said when.
"It has been five years that I have had this chain [around my feet]. Life in the prison is like entering in a pit of hell - you stay there and nobody takes care of you.
"I appealed two years ago, but none of my relatives are able to follow [up with legal counsel] so I stay here. I have five children, but they are very poor and can't make any appeal. Now when they come and visit, they just cry and cry, and I cry too… The youngest one is only eight.
"That time that I killed was the devil's intention, and it was stronger than me. Now that I am in prison, my heart is free and I have no bad feelings about my relatives.
"There was a referendum, there was an election and there was independence. Now there is a different president from Omar al-Bashir, but nothing has changed here in the prison. Probably outside, all of them were happy because of the new country, but in here, we were not happy - they changed the government but there was no change here."
