The search for a missing South Strabane Township man is intensifying. Sandra Duncan is the sister-in-law of 65-year-old John Ruffing who was last seen around three o’clock on Saturday afternoon at his home in Windsor Highlands. Duncan tells WJPA News that the family, along with police, have organized a Citizens Search team. Duncan says every day that her brother-in-law is missing becomes more crucial because of his medication needs. Duncan says he is on at least ten medications for various health issues, one of them being a blood thinner. She says if he is off of that medication for very long, he’ll begin developing blood clots. Ruffing, a Vietnam War veteran recently suffered a stroke and is believed to be traveling on foot, is described as being 5’9 and weighing about 200 pounds and was last seen wearing a red t-shirt with the phrase “Colonial Williamsburg,” tan shorts and black boots. Police are asking anyone with information to contact them.
