DURANT, Miss. -- A man suspected in the slayings of twohas been arrested and charged with capital murder in the shocking killing that rocked the small town communities where the women served, authorities said.
Rodney Earl Sanders, 46, of Kosciusko, Mississippi, was charged in the deaths of Sister Margaret Held and Sister Paula Merrill, Mississippi Department of Public Safety spokesman Warren Strain said late Friday. Both women were 68.
The women’s bodies were discovered Thursday after they failed to show up for work at a clinic in Lexington, Mississippi, about 10 miles from where they lived.
“Sanders was developed as a person of interest early on in the investigation,” Lt. Colonel Jimmy Jordan said in the statement.
Authorities said Sanders was being held in an undisclosed detention center pending a court appearance. They have not given any details on why they think Sanders killed the women or whether he knew them.
On Saturday, Strain told CBS News that authorities believe that robbery was the “least likely” motive for the killings and that a home invasion was also unlikely.
Sanders has served two prior prison stints, records show. In 1986, he was sentenced to six years for armed robbery in Holmes County. In February 2015, he was sentenced in Attala county to five years for felony DUI, though four years were suspended. He was paroled in July 2015 and was released on probation in September.
People who knew the nuns, longstanding pillars of the community known for their generosity and commitment to improving health care for the poor, have been grappling with why anyone would want to kill them.
Dr. Elias Abboud, the physician who oversees the clinic, said Saturday he called the office manager after he saw there was an arrest made to check if Sanders had been a patient at the clinic but he was not.
Sanders was also not known to the small congregation where Held and Merrill had led Bible study for years.
The Rev. Greg Plata, sacramental minister at St. Thomas Catholic Church in Lexington, said Saturday that he does not think people at the church knew Sanders.
Strain said Saturday he does not know whether Sanders is represented by an attorney. Authorities do not anticipate making any other arrests. Strain said “investigators believe Sanders acted alone.”
Merrill’s nephew, David Merrill, speaking by telephone from Stoneham, Massachusetts, said Saturday the family was “thankful” Sanders is off the streets.
“Nobody else is threatened by this individual. So there’s some relief there,” he said.
But the family still has to deal with the loss.
Merrill said he agrees with the idea of forgiveness and that is something his aunt would want for whoever killed her but it’s not that easy.
“I’m not as strong as my aunt. I don’t know if I’m capable of completely forgiving. I can have sympathy,” he said.
Merrill said he would not support the death penalty if Sanders were to be convicted but that decision will ultimately be made by the people in Mississippi. The capital murder charge leaves open the possibility that Sanders would face the death penalty but that determination would be made by prosecutors at a later stage.
The order of one of the nuns killed in Mississippi issued a statement thanking the law enforcement officers working on the case. Held belonged to the School Sisters of St. Francis.
Their U.S. Province Leadership Team offered its “deepest appreciation” to investigators and to “the hundreds of people and organizations who offered their prayers and words of support in the wake of the sisters’ deaths.”
Meanwhile, in the poverty-stricken Mississippi county where the two nuns were slain, forgiveness for their killer is hard to find, even if forgiveness is what the victims would have wanted.
“She doesn’t deserve to die like this, doing God’s work,” said Joe Morgan Jr., a 58-year-old former factory worker who has diabetes and was a patient of Merrill’s. “There’s something wrong with the world.”
Both women worked at the clinic, where they gave flu shots, dispensed insulin and provided other medical care for children and adults who couldn’t afford it.
Their stolen car was found abandoned a mile from their home, and there were signs of a break-in.
Authorities have not said how the women were killed, but the Rev. Plata said police told him they were stabbed.
Plata said both nuns’ religious communities have asked that people pray for the killer or killers. Asked about people’s struggles to forgive, the priest said: “Forgiveness is at the heart of being a Christian. Look at Jesus on the cross: ‘Father, forgive them for they know not what they do.’”
The clinic and the nuns’ home in Durant are in Holmes County, population 18,000. With 44 percent of its residents living in poverty, Holmes is the seventh-poorest county in America, according to the Census Bureau.
“A double homicide in a community this small and the fact that these two ladies were nuns - they actually spent their entire lives serving this community right here - I’m sure our community is completely devastated and grieving,” Assistant Police Chief James Lee told CBS.
The nuns’ death leaves a gaping hole in what was already a strapped health care system.
“This is a poor area, and they dignified those who are poor with outreach and respect for them,” Plata said.
The clinic provided about 25 percent of all medical care in the county, Abboud said.
Merrill’s sister Rosemarie, speaking by telephone from her Stoneham, Massachusetts, home, said her sister had been in Mississippi helping the poor since 1981.
Held - impressionable and idealistic - was committed to ending racism and poverty, according to an interview she did earlier with her order’s magazine.
“The invitation to come to Mississippi provided me with the setting in which I hoped to make a difference with my life. I came here because of a dream and a cause but I stayed her because of the people,” she said in the interview.
The women were lifelong friends who lived and worked together for years, said David Merrill.
“The word ‘sister’ has many meanings, and they fulfilled all of them,” he said.
