JACKSON, Miss. For 16 years, sisters Jamie and Gladys Scott have shared a life behind bars for their part in an $11 armed robbery. To share freedom, they must also share a kidney.
Mississippi Gov. Haley Barbour suspended the sisters' life sentences on Wednesday, but 36-year-old Gladys Scott's release is contingent on her giving a kidney to Jamie, her 38-year-old sister, who requires daily dialysis.
The sisters were convicted in 1994 of leading two men into an ambush in central Mississippi the year before. Three teenagers hit each man in the head with a shotgun and took their wallets making off with only $11, court records said.
Jamie and Gladys Scott were each convicted of two counts of armed robbery and sentenced to two life sentences.
"I think it's a victory," said the sisters' attorney, Chokwe Lumumba. "I talked to Gladys and she's elated about the news. I'm sure Jamie is, too."
Civil rights advocates have for years called for their release, saying the sentences were excessive. Those demands gained traction when Barbour asked the Mississippi Parole Board to take another look at the case.
The Scott sisters are eligible for parole in 2014, but Barbour said prison officials no longer think they are a threat to society and Jamie's medical condition is costing the state a lot of money.
Lumumba said he has no problem with the governor requiring Gladys to offer up her organ because "Gladys actually volunteered that as part of her petition."
Lumumba said it's not clear what caused the kidney failure, but it's likely a combination of different illnesses over the years.
Barbour spokesman Dan Turner told The Associated Press that Jamie Scott was released because she needs the transplant. He said Gladys Scott will be released if she agrees to donate her kidney because of the significant risk and recovery time.
"She wanted to do it," Turner said. "That wasn't something we introduced."
Barbour is a Republican in his second term who has been mentioned as a possible presidential contender in 2012. He said the parole board agreed with the indefinite suspension of their sentences, which is different from a pardon or commutation because it comes with conditions.
An "indefinite suspension of sentence" can be reversed if the conditions are not followed, but those requirements are usually things like meeting with a parole officer.
The Scott sisters have received significant public support from advocacy groups, including the NAACP, which called for their release. Hundreds of people marched through downtown Jackson from the state capital to the governor's mansion in September, chanting in unison that the women should be freed.
Still, their release won't be immediate.
Mississippi Department of Corrections Commissioner Chris Epps said late Wednesday that he had not received the order. He also said the women want to live with relatives in Florida, which requires approval from officials in that state.
In general, that process takes 45 days.
Mississippi NAACP President Derrick Johnson said the Scott sisters' release will be "a great victory for the state of Mississippi for two individuals who received an excessive sentence" and he has no problem with the kidney donation requirement because Gladys Scott volunteered.
"I think it's encouraging that she's willing to share a kidney so her sister can have a better quality life," Johnson said.
National NAACP President and CEO Benjamin Todd Jealous said the pardon represents the good that can come with the power of governors to commute sentences.
The organization worked to try to persuade Barbour who ended up agreeing that the sisters "did not deserve to spend one more day in prison," Jealous said.
"It's again proof that when people get engaged, keep the faith, we can win," Jealous said.
Barbour has used his power sparingly to free prisoners over the years, but some of his decisions have created a backlash.
Barbour outraged the family and friends of Jean Elizabeth Gillies, a University of Mississippi student who was raped, sodomized and strangled in 1986, when he granted a suspended sentence for her killer, Douglas Hodgkin.
He also angered others by granting a similar release to Michael Graham, who was serving a life sentence for murdering his ex-wife in 1989.
Both men had worked as prison trusties prisoners who earn privileges through good behavior at the governor's mansion, a tradition in Mississippi that dates back generations. Mississippi governors have often granted the trusties early releases.
