I'm going to go out on a limb here. I believe I know who Benjaman Kyle truly is. And the odd thing is that this missing person's name and face have already appeared here within these threads. Ben may have Powell relations several generations back, but I believe Benjaman is Donald Kenneth Shellenberger though the name was misspelled as Shelenberger. He is the same height as Benjaman, though listed at much thinner 160lbs. when he disappeared in 1994 at age 35, and after making arrangements with a friend to hike Mount Lemmon near Tucson. Shellenberger was listed as being 5'11" and having blue eyes and brown hair. Mr. Kyle and Donald Shelenberger have a strong resemblance, and neither is listed as having any tattoos. I found a Dr. Jeffry John Shellenberger in Tucson, whom I believe may be Benjaman's younger brother. I also believe he has a younger sister in Colorado Springs, CO by the name of Susie Shellenberger, an evangelist and author of 40 books. These are accomplished people in their fields which would fit in well with Benjaman being educated and articulate. I found the possible Colorado connection very interesting. With the extra weight Ben was carrying was lost, I thought he looked younger, and if indeed he is a match for Donald Shellenberger, he would be 54 today. That age seems to fit since he's shed a few pounds. Am encluding photos of Shelenberger, Kyle, Dr. Jeff Shellenburger and Susie Shellenberger. Sorry, I do not know how to make them all the same size. I spoke with Detective Crehan at Pima County Sheriff's Dept. today. Mr. Shelenberger was reported missing by the friend he was scheduled to go hiking with; however, Shellenberger never showed up. A search and rescue mission was carried out on Mount Lemmon with no results.
