Ronnie Barker, 72, and Beverly’s 69-year-old wife have not seen or heard of them since March 27, when they drove along Highway 95 in western Nevada. “They have literally disappeared into the air,” their daughter, Jennifer Whaley, told the WTHR. “It’s all flat. Everything is desert. So where did they go? Where did they go? They are located in the middle of the desert. You can see for miles and a 32-foot RV, towing a car, literally disappearing into the air. Where did they go?” The couple, who were due to return home to Indianapolis this week, had embarked on a cross-country road trip last month and were on their way to meet friends in Tucson, Arizona when they disappeared. Their daughter said they never called their friends in Tucson to tell them they would not be coming. The couple was driving in Tucson, Arizona when they disappeared. “The thought of not calling anyone is not them,” Whaley said. “They would have called and when they fall from the face of the earth, there is a problem.” The Barkers’ RV was last recorded by a surveillance camera along the Nevada Highway near Luning, about 150 miles southeast of Reno, at about 6:05 p.m. The last recorded pings from the couple’s cell phones were taken in nearby Coledale a little later. Both Bakers need medication, officials said. Relatives said there has been no activity on their credit cards since the last time they saw it. Authorities looking for the couple said they both have diabetes and need medication. They are traveling in a white 2015 Sunseeker RV with the Indiana C128H plate and towing a white 2020 Kia Soul, authorities said.
