The Yadkin County Sheriff's Office arrested a man Tuesday morning after he confessed to shooting and killing his wife and neighbor with a shotgun, officers said. Sheriff Mike Cain said Robert Lane Main, 51, had been lying in bed with his wife, Linda Kathleen, between 11 p.m. and midnight at their home at 1034 U.S. 601 South. He said the couple seemed to have gone along with a normal routine that night. "They had supper and everything," Cain said. Sometime between 11 p.m. and midnight, Cain said, Robert Main got out of bed, located his shotgun and shot and killed Linda Main while she slept in the bed. Authorities said Robert Main left his home and "drove around." Robert Main's 70-year-old mother, Ivalee Vines, was staying with the couple. Authorities said Vines heard the shotgun blast and saw her son leave with the weapon. Cain said Vines asked her son what he was doing and where he was going, but there was no reply as he left. Vines went into the couple's bedroom and discovered Linda Main's body. Authorities said Vines then drove to Robert and Linda's son, James Main's, house. While Vines was gone, Robert Main returned. Authorities say he parked in his next-door neighbor's driveway hitting two vehicles. According to sheriff's reports, Robert Main entered his neighbor Mitchell Todd Stimpson's house at 1032 U.S. 601 South, and shot and killed Stimpson while he was asleep on his couch. Cain said Robert Main exited the house, got back into his van and began driving through Yadkin County and into Wilkes County. After Robert Main left the Stimpson home, James Main arrived at his parent's home and discovered his mother's body. Deputies were called around 2 a.m. When deputies arrived at the Main's house, they noticed the two damaged vehicles in Stimpson's driveway. Cain said a deputy knocked on Stimpson's door, which awoke Stimpson's 13-year-old daughter. The deputy entered the Stimpson house after hearing the teenage girl scream. Cain said she had just discovered her father's body."She's lost everybody she's got except for her grandparents in the last year and a half," Cain said about Stimpson's daughter. He said within the last two years, Stimpson's wife had died of cancer and his son had committed suicide. The daughter is now staying with her grandparents. While authorities were at the two crime scenes, Robert Main was stopped by a Wilkes County deputy. Cain said he didn't know the reason why Robert Main's vehicle was stopped. Using standard procedure for a traffic stop, the deputy contacted Yadkin County dispatch to see if any warrants were out for Robert Main. No warrants were present so the deputy let Robert Main go. Cain said after the deputy had radioed Yadkin, dispatch remembered the description. "Dispatch recognized the description and contacted Wilkes and the surrounding counties," Cain said. Within an hour, Cain said, Robert Main had been stopped and detained by the Watauga County Sheriff's Office. Cain said his deputies interviewed Robert Main at the Watauga sheriff's office. "He admitted to it," Cain said, adding that Robert Main had the shotgun with him when he was stopped. Cain said there was had been no arguments reported from the Main's house. He said his office had never been called out to home before. Maj. Danny Widener said his department has not found any prior criminal records for Robert Main so far, but authorities said the family told them that Robert Main did try to commit himself Monday. Cain said the family told him that Robert Main couldn't voluntary commit himself because it would cost him $500 to $800 per day and he didn't have insurance. Cain said no evidence has been found to prove Robert Main tried to commit himself to any facility. "It's a shame he didn't get some kind of help," Cain said. Cain said it had been reported to him that Robert Main was upset about a relationship between the two victims. Authorities said there is no evidence to support rumors that Stimpson and Linda Main had an affair. "It's speculation and a rumor," Cain said. "I think that is mental health issues on him." He said there is no official motive known. "I don't know if we ever will know," he said. Robert Main is currently being held in the Yadkin County Jail without bond. Widener said he could be transfered to Central Prison in Raleigh following a psychological evaluation. Robert Main has been charged with two counts of first-degree murder and one count of first-degree burglary. The case is still under investigation. The Main double murder marks the first homicide in Yadkin County since 2005.
