Introduction
The case I chose to write on is based on a DVD that we watched in class called ‘Beaten by a hair’. In this case, a woman was reported missing after she went to work and never returned home.

Only a tiny amount of iron is required to catalyze the reaction” (Helmenstine, 2012). The use of luminol revealed that there were blood stains on the bed sheets and suspected that the woman was killed in her bedroom and that she did not go to work that day or leave the house.
Upon further analysis of the woman’s bedroom, the forensic officers used a chemical called amido black. Amido black is a protein dye that is sensitive to the protein in blood and when it makes contact stains a latent blue-black colour.

The forensic officers also performed an ultraviolet light test which was used to reveal trace evidence such as vaginal fluid, urine, semen, or saliva. The ultraviolet test is usually done before using chemicals such as luminol to see if there are any fibers to be found and used first. However the officers were not able to find anything, but this method was useful to them because they could not find any evidence to prove that
