Livor Mortis: Scans From Gresham's Colour Atlas of Forensic Pathology (1975)
A Colour Atlas of Forensic Pathology, first issued in 1975 as part of the Wolfe Medical Atlases series, was written by G. Austin Gresham as a field pocket reference for pathologists in training. Gresham was a Cambridge professor of morbid anatomy and histopathology, as well as a Home Office pathologist. Livor mortis, known also as postmortem lividity or hypostasis, occurs when blood settles in the body's lowest areas after death, producing pink through dark-purple skin discoloration. It may appear from 20 minutes to 2 hours after death, becomes apparent during the following hours, and generally fixes within 8 to 12 hours, after which pressure no longer causes it to fade. Investigators use fixed lividity on the incorrect side of a body to indicate that it was moved after death, while unusual coloration may suggest causes of death including carbon monoxide poisoning. The atlas addresses all areas of forensic pathology, so not every figure depicts lividity; some show bruising or other findings. |
