Of all evidence that could have been left behind, a tie is the most effective in delivering the story of it’s owner. A tie is an object that is washed less in comparison to other items of clothing. Investigators of the case soon realized this fact and tested the particles on the tie using modern day science. The particles on the tie suggest that this tie was in daily use for an extended period of time without a thorough wash. On the tie, investigators found tiny shards of pure titanium. In the 1970’s, pure titanium was seldom in use. At first, investigators thought that Cooper could have been in the military or in the airliner business. But what they did not know was that pure titanium was not used for planes or military.

The pollen was identified to be Lycopodium, and it was coated with materials that were often used in pill coverings. Evidence suggests that Cooper was taking a pill a regular basis during work hours. However, a medicine using Lycopodium is not heard of. That being said, there is a type of addictive drug that might use this substance, which could also connect Cooper to this crime. Cooper could possibly have needed money to fulfill his need for this drug, and he probably thought the best way to get that money was to hijack a plane (Kayne,…show more content… He was nicknamed “Dan” by his colleagues and served as a smokejumper in the 1950’s. He fit the physical description of D.B. Cooper, and he had a crazy alibi. He said that when the Cooper hijacking took place, “he was raising small children in a mud hut in Nepal, and writing his accounts of American atrocities in Vietnam.” However, his crazy alibi was not the most wild thing about his case. During a Boeing promotional exercise, he parachuted out of a plane wearing a business suit, while carrying a 50 pound sack of flour strapped to his legs. In other words, he pulled off the same stunt that D.B. Cooper would later attempt. Though Peterson seemed like a practical suspect, investigators could not acquire enough evidence to prove that he was Dan Cooper (Smith,
