Summary of "Tech Detectives" (Unit 2, Lesson A).

     This reading is the story and method that police detectives extracte and solve crimes using the latest technologies, DNA analysis and CT imaging technology. Specifically, in the text there are three real mysterious cases in different time and countries; in Australia, Arizona, and Italian Alps. These cases help us understand and feel more friendly to the life of detectives.
     The first solved case is a robbery in Australia in 2001. The case's suspect was arrested in 2009, after eight years of happening the crime by database from a leech. In Tasmania, Two men robbed several hundred dollars in old waman's house. Soon after they got away, a leech filled with blood was discovered in that place. Surprisingly, eight years later, a suspect was arrested on drug charge, but it was told that he was the robber because his DNA was same with taken from the leech. The detectives's speculation is when they was traveling through the woods, one of robbers was sucked by the leech.

     Likewise, there is the case that could be solved by nature, plant "palo verde tree". In 1992, a murder crashed the victim to his truck and there was left over a oager at the scene of the crime, Phoenix in the state capital of Arizona. The suspect insisted on he carried the victim by his truck, but she had robbed him, so there had been a pager there. However, seed pods, the fruit of the palo verde tree was found in his truck. Therefore, a geneticist of Arizona in Tucson investigated that seed and revealed it was individual plants and unique patterns of DNA. The murder was convicted of colliding a person and the one specific tree, too.

       Conversely, The last case was solved by body mark and CT imaging in past time. An Iceman, Europe's oldest mummy was killed in Bolzano, Italy where scientists speculated that he had lived there about 5,300 years ago. After then in 1991, a hiker of Alps found out the iceman. CT imaging technology and X-ray was the most important means to scientists to collect clues of reason how and why he was killed. There was an arrowhead buried in the Iceman's left shoulder, so scientists realized there was an attack of enemies behind him. Also a wound on his hand led scientists that he was chased and there was a fight between him and enemies. In conclusion of a supposition is that Iceman chased by threat and he escaped and he think he was safe but murder killed him behind.

      Through these three real examples, We could know what is detectives's work by the latest technology; DNA analysis, CT imaging technology, even X-ray. Both From the present and from the past, the mysteries and crimes could solved by one piece of clues because there are the tech and detectives now.
