Jane Kozik says "Dr. Fogg was murdered. Take a look at that petechial hemorrhaging here" and points to the bruise on his neck. Dr. Fogg eyes are closed. A petechial hemorrhage is a tiny pinpoint red mark which occurs when blood leaks from the tiny capillaries in the eyes. The forensic pathologist usually needs a very good light source and maybe even a magnifying glass to detect petechial hemorrhages. They range in size from the size of a speck of dust to around two millimeters. It is true, however, that bruising or contusions on his neck can be a sign of strangulation, but that's a different buzz word.
