Dr. Melba Ketchum announced she will be working on teeth and bone samples in pursuit of Bigfoot DNA. The technique she will be using is a technique taught to her from a Dr. Pat. According to Dr. Ketchum, Dr. Pat has never failed at getting DNA from bone and has developed the extraction techniques that have identified people for the military, including the soldiers buried in the Tomb of the Unknown.
As a side note, anonymity of the entombed soldier is key to the symbolism of the monument: since the identity is unknown, it could theoretically be the tomb of anyone who fell in service of the nation in question, and therefore serves as a monument to all of their sacrifices. Symbolism is great, but families their fallen identified and post-Vietnam soldiers may never be unknown again. You can read about the last identified soldier in this Washington Post article.

Getting back to Dr. Ketchum, she seems very excited about the techniques and makes a distinction between forensic scientist and academic scientist. Read an excerpt from her announcement on facebook below.
