A skeletonized bloodstain refers to a bloodstain that has dried over time, leaving behind a distinct outline or pattern resembling a skeletal structure. This term is often used in forensic investigations to describe older bloodstains that have undergone significant evaporation and have distinct edges.
Low Velocity Impact Spatter (LVIS) -- A bloodstain pattern that is caused by a low velocity impact/force to a blood source. Medium Velocity Impact Spatter (MVIS) -- A bloodstain pattern caused by a medium velocity impact/force to a blood source.
Dr. Paul L. Kirk, a forensic scientist, conducted studies in the 1930s that demonstrated the importance of blood evidence in solving crimes. His work laid the foundation for bloodstain pattern analysis and the use of blood evidence in criminal investigations.
The most common type of bloodstain pattern at a crime scene is typically transfer stains. These are created when a wet, bloody object comes into contact with a surface, leaving a recognizable outline or shape. Transfer stains can provide valuable information about the sequence of events and the movements of individuals involved in the incident.
International Association of Bloodstain Pattern Analysts was created in 1983.

Yes, the Takayama test can determine if a bloodstain is human or animal in origin based on the presence of hemoglobin. The test uses chemicals that react with hemoglobin to produce a distinct color change, indicating the presence of human blood.
As a science major and one who is interested in a possible career in forensic science research, I was reading about this particular specialty in the field. Not much job information was available from my initial search except that I noticed that there is an opening for a Bloodstain Pattern Analyst with the Ontario Police Department and they state the salary is between $1,500 - $1,900 per week.
