Local law enforcement detectives learn about blood spatter
KENNEWICK, Wash. -- More than 20 detectives from local law enforcement agencies spent the week at Kennewick Police Department for a special class on blood spatter analysis.
Detectives learned how to read the blood left behind at a crime scene to determine where a person was hit or shot, and what weapons were used.
"Detectives should be able to walk into a crime scene, recognize blood evidence at the scene, and study it and ultimately render an opinion about how it was created and what mechanism was used to create it,"says Detective Dan Christman, with the Bothell Police Department, who is also a blood stain expert teaching the 40 hour class.
Detective Curt Oja, with the Yakima Police Department, was one of four detectives sent for the week long class. "We learned how many times the person was injured or where they were bleeding from. We can use that to determine what kind of weapon was involved," says Oja.
The week-long class typically costs $399 a person, but because of it's importance, it was hosted by the Kennewick Police Department and paid for by the Fraternal Order of Police.
It is so affective, a prosecutor from Holland came in for the week as well. "As a prosecutor, I get the reports from the detectives, saying what happened at the crime scene and after a course like this its easier for me to understand what they're talking about," says Petra Truppelaar.
