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.
