-- A man has been arrested in connection with the killing of two nuns in Mississippi this week, the state's Department of Public Safety announced late Friday in a statement.
"Sanders was developed as a person of interest early on in the investigation,” said Mississippi Bureau of Investigations director Lt. Colonel Jimmy Jordan in the statement. “With the cooperation of the Durant and Kosciusko Police Departments, Holmes County Sheriff’s Department and the Attorney General Office this heinous crime has been resolved.”
After an "exhaustive interview" Friday night, Mississippi Bureau of Investigations agents were able to develop enough information to charge Sanders, according to the statement.
"Information was developed on his whereabouts during the course of the investigation. Sanders was located, questioned, and then brought into custody and charged," Warren Strain, communications director for the Mississippi Department of Public Safety, told ABC News early Saturday morning.
There was no incident when Sanders was arrested.
Strain also told ABC News it is believed Sanders acted alone.
Police initially said the nuns may have been victims of a break-in and car theft. Their bodies were found by police when they did not report to work, the Catholic Diocese of Jackson said.
"She was so good to the people down there and they just loved her," Merrill's sister, Rosemarie Merrill, told ABC affiliate WAPT in Jackson.
Authorities did not release a cause of death but Rev. Greg Plata said police told him the women were stabbed, The AP reported.
A car apparently taken from the nuns' home was found Thursday night about one mile away from the crime scene. The car was taken to the crime lab to be processed.
Sanders is “not quite homeless,” but is "nomadic,” said Strain. He split his time between the Mississippi communities of Lexington, Durant, and Kosciusko.
Strain said the public was a great help to the investigation and there is a "good possibility" that the $22,500 reward will be distributed after an intensive vetting process.
Sanders is being held in an undisclosed detention center awaiting his initial court appearance, to be set on Monday, Strain said.
A wake will be held Sunday evening at the St. Thomas Church in Lexington and a memorial mass will be held Monday morning at the Cathedral of Saint Peter the Apostle in Jackson.
