The longer dimension of the spatter is the length (I think).
Correct. (If you switch up the numbers for length and width it will give you an error when you put it into the arcsin(width/length) equation, so that's a nice check!)

How do you calculate the velocity of blood from it's splatter? Or is it only possible to classify it as high, medium, or low velocity?

pretty sure that's the only way...I have never had anything aside from high medium or low, and i'm pretty sure any other way would just be a surefire method of losing time

does anyone know how to read a mass spec graph? I am hopelessly confused on this...

With so many new innovations going on in forensics, this is just one thing that so many people have questions on. It brings up the question that are the people who are solving crime actually know what they are doing or is it just a matter of having certain questions answered. I think researchers and programs like http://www.forensicscience.gov/ are doing everything they can to innovate and help make things like reading a mass spec graph easier. I think it's an amazing field to pursue as working for a forensic team would bring you a new challenge everyday and you would have to be on your feet at all times. If you're like me and always thought about getting into the field I would check out http://www.bestforensicscienceschools.com which answers any questions you may have about the field, different programs available, career opportunities etc. I would say getting further education in this industry can help you solve more questions you have and enable you to pursue a career that is full of excitement and always innovating.

Yeah, I have no idea how many we left blank. We didn't have enough time to make sense of our giant list of answers at the end, so we ended up having to choose our final suspect essentially fifty-fifty from the two names that showed up most often. We ended up getting 7th.

I'm not sure how we got second. My partner guessed quite a lot and our analysis had like 6 things under it. I thought we failed O_o
