PHOTOS: ALEXANDER GARDNER TOP ; NATIONAL GEOGRAPHIC TELEVISION NAT GEO CHANNEL THE TRAGIC DEATH of Abraham Lincoln is hardly a mystery. What isn't clear, however, is the state of the Presi- dent's health at the time of his assassination. His gaunt frame and prematurely aged looks have led to speculation that he was gravely ill and possibly dying of cancer. In Lincoln's Secret Killer? diagnosis expert John Sotos sets out to prove it. Follow him as he tracks down relics from Lincoln's past---including bloodstained fabric that may harbor traces of DNA---and attempts to have them tested for the first time ever, by geneticists in Ohio and New Zealand. Lincoln's Secret Killer? airs February 21 at 10 p.m. ET on the National Geographic Channel. THIS MONTH Lincoln's Secret Killer?
