In room 4, we are investigating into a crime. Somebody was trying to steal something, and while they were leaving, they cut themselves while jumping through a window. We found some of their bloody clothing, and we started our work on the crime. Using CCTV footage, we narrowed it down to four people. We still haven't found out what they stole. Then we started our work on who's blood it was.
First off, we put some water on the bloody cloth. Then, we put that on the slide, and then put the slide under a microscope. On the first scope, we could see a pattern of red and a hairy substance. Then, when we tried the second scope, we saw what we saw on the second scope, but bigger. We couldn't see it on the third scope, so we tried to see how the blood reacted.
First, we put Anti-A, Anti-B, and Anti-RH, against their chosen blood. They all reacted differently, put due to research, we figured out that the robbers, blood was A+. We checked through all the suspects, but we figured out that the robber was Suspect 3.
