Dr. John Soto may get a chance to prove his theory that Lincoln would have possibly died of cancer during his second term if he wasn't assassinated. Sotos has long theorized that Lincoln had MENIIB, a fatal cancer gene. A Civil War museum in Philidelphia possesses a strip of a pillowcase stained with Lincoln's blood. The pillow is from the Peterson House, where Lincoln lay suffering from the wounds of the assassination. The museum is called the Grand Army of the Republic Museum and Library.
The museum's board of directors voted unanimously to possibly answer the question of Lincoln's mortality once and for all. Museum President Eric Schmincke says "we do not want to damage it to the point that it doesn't exist anymore." Now, the museum says it will find the right experts to extract a few delicate fibers from the pillowcase that may hold an unwritten chapter of American history.
Soto has developed some proof for his hypothesis. In his book Physical Lincoln, Soto has used photographs and other evidence that proves his theory to a point. Now he is seeking that final bit of evidence.
Here is the link to Soto's website and book.
