North Carolina's highest court is reviewing whether justice means the death penalty for a survivor of El Salvador's blood-soaked civil war of the 1980s who strangled and then decapitated his estranged wife.

The state's Supreme Court hears oral arguments Monday on whether the state can execute 41-year-old Juan Carlos Rodriguez of Winston-Salem for the 2010 murder of his wife, Maria. The high court automatically reviews death cases.

North Carolina is rare among southern states in that it hasn't had an execution in more than a decade because of various legal challenges. While the state has continued to suffer 500 to 600 murders a year, prosecutors have sought the death penalty only a handful of times each year and juries have condemned killers in only a fraction of those cases.

Rodriguez's children told investigators their father beat and bloodied Maria Rodriguez after she told them she was leaving in November 2010. He tossed the woman's still-breathing body over his shoulder, placed her in his vehicle, and said he was taking her to a hospital. Maria's body and severed head were found at different locations three weeks later, after Juan was already jailed for her kidnapping.

Justices are holding hearings in the case for the second time in almost exactly a year. Monday's hearing comes after the U.S. Supreme Court ruled this spring that states needed to use current medical standards in deciding whether a killer is so mentally disabled he can't be executed. The U.S. constitution bans "cruel and unusual punishments," and that has been interpreted to prohibit executing people with severe mental shortcomings.

Rodriguez's IQ was estimated several times at below 70, a threshold for significantly impaired intellectual functioning. But accused killers in North Carolina also must show significant inability to adapt to daily life and that their mental handicaps were evident before adulthood.

Jailed former South Korean President Park Geun-hye called herself a victim of "political revenge" in her first public remarks since her high-profile corruption trial began in May, news reports said, as her lawyers resigned Monday in an apparent protest over the court's decision to extend her detention.

The moves appeared to be aimed at applying pressure on the court and rallying her small number of conservative supporters in a development that could intensify a political divide and delay the trial.

The Seoul Central District Court said Park's seven lawyers resigned collectively Monday, three days after it approved an additional six-month arrest warrant for her. Court officials said they will appoint lawyers for Park if her lawyers do not reverse their decision or Park doesn't name a new defense.

A verdict had been expected possibly before the end of the year. If Park has new lawyers, the trial is likely to be delayed because they will need to become familiarized with a massive amount of court and investigation documents, reportedly estimated at more than 100,000 pages.

Park, who was removed from office and arrested in late March, faces a range of corruption and other charges that could lead to a lengthy prison term. Among the key charges are that she colluded with a longtime friend to take tens of millions of dollars from companies in bribes and extortion.

During a court session Monday, Park reiterated her innocence, saying she hopes she will be the last person to suffer "political revenge" orchestrated in the name of justice. She also described her past months of detention as a "wretched and miserable time," and said she had never abused her power or accepted illicit requests for favors while in office, Yonhap news agency reported.

Other South Korean media carried similar reports about Park's comments. The Seoul court said it couldn't confirm them, while calls to her former main lawyer were not answered.

Park denied most of the allegations many times before her March arrest, but Monday's comments were her first in court since her trial started.
