trajectory lab

QUESTIONS! XD
WHAT ARE THE METHODS USED BY FORENSIC SCIENTISTS TO DETERMINE OTHER CRITICAL INFO ABOUT THE SEEN OF A CRIME? HOW MIGHT THIS LAB PREP YOU FOR YOUR MISSION?
sorry about that all being in caps, but anyways back to the subject, so again like in the powder lab, i can't truly say because a) I am not a forensic scientist and b) i don't know any one who is a forensic scientist. so i really cant say for sure what is true and what is wrong. but what we did was we measured how the width/height of the splatter or bullet hole then we used soacahtoa math (i think i spelled that wrong...) to determine the angle it fell from. and there might be blood splatters at the crime scene.

powder lab

question(s)
what are the methods that are used by forensic scientist to determine the nature of and unknown substance (like white powder)? how might this lab might prep you for this mission?
well i can to an extent answer the first question but it will be hazy, we could be using different methods by adding substances to the powders, and heating them up, but still we could be useing the exscat same methouds, i don't know.
this could prep us for our misson because we could find some kind of white powder on the scene that we need to identfy.

fiber lab/THIS COMPUTER HATES ME!

i tried to post a video but the computer would not let me so here goes me writing it! :D
for fiber lab, you can use fibers to identify a person to a lab if there were people to see what the suspect was wearing. or if you know what the suspect was wearing the night of the crime you could link to the that way. and you can tell what is what comparing them under a microscope very well, or even burning them if you have enough.
To prep. us for our mission, we could find a piece of fiber at the scene, and get a list of peple who are suspects and what they were wearing. and useing the information we have we could disern what kind of fiber was at the scene and use that information to like the crime to a person.

urine analysis

sample A has some similarities to samples C and B like the ph in A is close to the ph in C and they looked the same in the glucose test. it could mean that they come from the same person but i am not 100% certain. if done right i am pretty sure that you might be able to link a suspect to a crime.
