How can investigators use angle of impact to help solve crimes?
Investigators can use the angle of impact of blood spatter to help determine the direction from which the blood originated. By analyzing the angle, they can reconstruct the events that led to the blood spatter, helping to establish the position and movement of individuals involved in the crime. This information can provide crucial evidence to support or challenge witness statements and suspects' alibis.
What was the earliest known use of blood spatter evidence?
The earliest known use of blood spatter evidence in a forensic context dates back to the late 19th century, particularly in 1895 when German scientist Hans Gross published a comprehensive treatise on criminalistics. His work laid the foundation for the systematic examination of blood patterns at crime scenes. However, the scientific study of blood spatter analysis gained formal recognition and development in the mid-20th century, particularly through the contributions of forensic experts like Dr. Paul Kirk.

How does forensic use blood spatter information?
Lots of things. They can determin the angle the blood came from, the velocity, they can basically recreate the entire crime. you can also tell in some cases what tool or weapon waas used, a direction the criminal went, if someone was standing in front of the murder victim. tons of crap
Does blood spatter velocity indicate a crime of passion?
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.
How can evidence prove a crime suspect's guilt or innocence?
Types of evidence from a crime scene, that investigators will use to solve crimes, is blood evidence. Blood spatter, blood type, weapons, fingerprints, hair samples, and body fluids can all be important factors in solving a crime.
What is the relevance of trigonometry in criminology?
Trigonometry is used in many situations and jobs in life, including architects, surveyors, astronauts, physicists, engineers and even crime scene investigators. The latter use trigonometry for example to calculate a projectile's trajectory, to estimate what might have caused a collision in a car accident or how did an object fall down from somewhere (for example from a rooftop).
HOW TRIGONOMETRY USE BY CRIMINOLOGY?
Trigonometry is used in criminology to analyze crime scene measurements, such as bullet trajectories, blood spatter patterns, and accident reconstruction. By applying trigonometric principles, investigators can determine the angles, distances, and directions involved in the crime, which are essential for solving cases and gathering evidence.
How would you remove paint spatter from an acoustic guitar?
To remove paint spatter from an acoustic guitar, first, gently scrape off any excess paint with a plastic card or a soft tool to avoid scratching the finish. Then, use a soft cloth slightly dampened with a mixture of water and mild soap to carefully blot the spatter, avoiding excess moisture. For stubborn spots, you can try a small amount of isopropyl alcohol on a cotton swab, but test it on an inconspicuous area first. Always ensure the guitar is completely dry before storing it.
