Abstract
During possible violent crimes, evidence like blood is left behind. Previous experiments didn’t use the common surfaces such as concrete, drywall, and hardwood flooring. Testing on more surfaces is important, especially in criminal forensics, in order to give more information to solve criminal acts. The purpose of this experiment is to test blood detectors on several different surfaces after blood has been applied and then cleaned off with various common household cleaners. Through this experiment, locally sourced pig’s blood, which is similar tohuman’s blood, was spread on squares concrete, wood flooring,and drywall, and then cleaned with Clorox bleach, Dawn soap and hot water, Mr. Clean Magic Eraser, and Mrs. Meyer’s Household Cleaner. Bluestar and luminol were then applied to the surface. Results showed that, throughout the different surfaces, cleaners were unable to clear all of the blood. Luminol and Bluestar were successful in all cases of showing where blood was spread on a surface
