02 - Intro to Forensic Science: Left at the Scene of the Crime
Experiment Procedures: Blood Splatter Analysis 1. Work with one item at a time to avoid cross contamination or sample mix-up. EXAMINE the object for the visible red-brown staining and general characteris- tics. 2. PLACE the item on a flat, clean surface. 3. Use the fine-mist sprayer to gently SPRAY the targeted area on the object with the Leucocrystal Violet (LCV) solution from a distance of about 2-3 inches. 4. ALLOW the samples to sit for 30 seconds before analyzing. LCV generates a purple/violet color and indicates the presence of blood. 5. RECORD your sample ID and observations in the Table, below:
