Forensic science is a fascinating field that has evolved dramatically over the last few decades. There are many techniques that forensic scientists use to solve crimes before or after someone has been arrested and obtained Minnesota bail bonds.
Forensic pathology refers to the examination of a body. When a death seems to be suspicious, a pathologist is employed to ascertain the cause of the person’s death. They look for proof of injuries on the outside and inside of a victim’s body.
