The blood came from shabab. thats why its black.
Yes, blood type is reliable and accurate. When forensic scientists collect blood from the crime scene and/or the victim (blood is an example of "physical evidence"), they use the blood to match it up with whoever was at the crime scene. It could belong to either the victim--who might have died a violent death--or it could belong to a suspect.
Not necessarily any high-velocity wound would cause splatter. But it IS an indication that it could be a possibility. The phrase "blood spatter velocity" is not a phrase or term used by blood spatter analysts. By the way, the correct term is, in fact, "spatter" and not "splatter" as written in the answer above. Force applied to liquid blood will cause the liquid to break up into smaller droplets. Imagine blood running down your finger and dripping off the end. The force of gravity isn't very much, relatively speaking, so the blood drop is large. Little force equals larger-sized drops. Now imagine having blood in your mouth and then coughing or sneezing. The force behind the expulsion of air will break up the blood drops into much smaller sizes. We see this also with very forceful crime events such as gunshot exit wounds or forceful beatings, especially with objects such as bats, prybars, etc. So, the presence of very small droplets of blood in a bloodstain pattern is indicative of an application of a high force. The "crime of passion" part of the question suggests an intent of some kind, and one can rarely deduce actual intent from the appearance of bloodstain patterns. Crime scene reconstructions use science to ascertain what happened. They do not attempt to determine the motivation for why it happened.
It is such a bad crime that the average criminal even thinks it is disgusting and horrible. Raping a young girl would be a great example. Things that the average person could not comprehend how a persson could do something that low. Bernie Maddoff's crime are another example.
forensic scientists who are in the lab test DNA found at a crime scene to try and link a suspect to the crime scene. They test things like blood, hair, skin cells, saliva, etc.
