Did John Wilkes Booth get away?

As the story goes, about 2 weeks after shooting President Lincoln, John Wilkes Booth was killed in a barn in rural VA. But there has always been a controversy about the legitimacy of this story. Nobody denies that somebody was shot in that barn, but whether or not it was actually JWB was never proven 100%. Somebody is currently laying in an unmarked grave believed to be JWB, historians now want to find out using DNA testing whether or not it actually is the same person as the gravestone says.

From the article:
Now, Booth's descendants have authorized the exhumation of John Wilkes Booth's brother, Shakespearean actor Edwin Booth, to get a DNA sample and close the books on the case. The DNA will be compared with a sample from vertebrae of the man killed in the barn. The body itself is buried but bone samples are in the collection of the National Museum of Medicine and the (incredible) Mutter Museum in Philadelphia.
