問題詳情

請依下文回答第 34 題至第 37 題Solving crimes is one of the most important jobs of law enforcement. Improvements in crime technology helpdetectives solve crimes faster today. For example, crime labs have new kinds of DNA testing, which can identify bodyfluids such as blood, sweat, and saliva. There are also new kinds of fingerprint testing. In the past, fingerprint testingwas only helpful if the fingerprints from the crime scene could be matched with “prints” that were already on file.People whose fingerprints were not on file couldn’t be identified in this way, and as a result, many crimes had not beensolved.However, the newest kind of fingerprint testing can do much more than simply record a fingerprint pattern. It canprovide additional information, such as the age and sex of its owner. The fingerprints can reveal if the person takesmedication, too. But the latest technology does even more. It can even get fingerprints from fabric, for example,blankets or curtains. In a recent case, the police in Tacoma, Washington, found the body of a woman who had beenmurdered in her bedroom. There was no witness, and her apartment had few clues. The only real evidence did not seemvery helpful. The victim’s bed sheet had some of her blood on it and looked as if someone had wiped his hands. At thetime of the murder, it was impossible to identify a fingerprint from fabric. The detectives were unable to use theevidence, but they saved it anyway. Then they called Eric Berg, who was not only a forensic expert, but a computerexpert, too. He had spent years developing computer software to improve crime scene photos. Eric used his computerto make the palm print more apparent. When he was done, he gave the evidence to the detectives. The detectives founda man whose palm print matched a print on file. Only two hours later the suspect was arrested and put in jail.
