High School Student Discovers the Best Way to Hide Evidence of Murder

eminent schooling soph Brynn Myers determine to tackle a forensics topic for her science fairish task this year . And in the process , she discovered how to commit murder and obscure the evidence thoroughly .

Myers , a 16 - year - old from Missouri , wanted to come up the most good way to hide pedigree after splattering it everywhere . So she put a few drops of cow ’s blood on several pieces of cotton cloth for her study , and used three kinds of cleanser to wash the cloths . She presented the results last week at theIntel International Science and Engineering Fairin Pittsburgh .

Writing for Student Science blog Eureka ! Lab , Bethany Brookshire describes the experiment :

She focused on three common household cleaners : blanching agent , laundry detergent and an oxygen - boosting cleanser . Chlorine blanching agent is used to remove deep - seated mark and to disinfect . Most laundry detergent contain surfactants — chemical that make it easier for subject matter such as the scandal on your wearing apparel to resolve into the wash water . Oxygen dry cleaner turn back chemicals such as hydrogen peroxide , which also can disinfect surfaces …

When it amount to visible stains , the oxygen cleaner cultivate best . It took only a single wash to absent all optical signs of rake from the cotton washcloths . The bleach batch was still stained after the first and 2d wash , but came out clean after a third political campaign . Laundry detergent left a pile of blood - defile cloths — even after three race .

After running a few forensic test on the cloths , however , Myers found that the blood was still detectable on them even when it was n’t seeable . Still , the oxygen cleaner shoot down some of the toughest forensics tests . Myers may have discovered the ultimate murder cleanup dick . But she apprise that her discoveries are actually a boon for forensic scientific discipline .
