Explain the rationale for how you chose to move through a particular room. When I went through each room, I tried to move in a way that wouldn't mess anything up. Brandl (2018) talks about how even the smallest movement in the wrong spot can ruin evidence, so I kept that in mind the whole time. That is why in the home office, I walked straight through the center instead of wandering around the edges where papers, footprints, or anything small might be. In Crime Scene 2, I approached the body from the outside of the room, not straight through the middle. Brandl (2018) mentions that investigators should follow the least intrusive path so that blood patterns, impressions, or anything that could help explain what happened stays untouched. So basically, I moved slowly, watched where I stepped, and only went where I absolutely needed to go. Explain the rationale for your choice in sealing the evidence bags. I sealed the evidence bags to keep everything protected and to make sure the chain of custody stays clean. Brandl (2018) explains that once we collect something, it has to be packaged and sealed so nobody can add, remove, or contaminate anything. Sealing it right away keeps the item exactly how it was found. Plus, the seal is proof that nobody has tampered with it. If the tape is broken, it is clearly obvious. Brandl (2018) points out that this is important for the court because they want to know the evidence was handled the right way from the start
