How long can a body be kept in a freezer

will delay ...... because, the presumed time of death of the body is based on a combination of characteristics (i.e., forensic pathology, forensic clinics and forensic toxicology, etc.) to make a judgment. After refrigeration can indeed delay the time of death, affecting the judgment, but from the temperature as well as the victim's clothing and other aspects of the traces of refrigeration can be judged, in contrast to the use of electric blankets and other items heated instead of not easy to be detected ...... judgment of the time of death roughly there are these: 1, protein changes: this is the most important means of judgment in the Within 30 hours of the victim's death, the body proteins will condense and harden, but after 72 hours will gradually soften. But there is a special case, that is, after strenuous exercise of the deceased body will quickly lose temperature and harden, after corruption 2, body temperature: this is also the main means, but many ways (such as electric blankets ...... I wrote that case) will change the temperature of the body and affect the time. The following formula is commonly used to infer the time of death: room temperature (98.6 degrees Fahrenheit or 37 degrees Celsius) a rectal temperature of the body / l.5 = approximate time elapsed since death (generally quasi some with Fahrenheit) attached Fahrenheit and Celsius conversion formula: 5 (F-50) = 9 (C-10), C for the Celsius, F for the Fahrenheit 3, look at the digestive material in the body, the food digested by the stomach in about 2 hours will be all the way to the small intestine. 4, the release of drugs: If the victim body ingested drugs (mainly slow-release class), then the forensic pathologist can be based on the release of drugs in the body to determine the time 5, the condition of the body spots: mainly divided into the period of the fall (generally in the post mortem 2 to 4 hours after the beginning of the emergence of the), diffusion period (after 12 hours, the fast for 8-10 hours) and the wet period (after the second day in general), but the method of judgment there may be a miscarriage of justice Condition appears. 6, the amount of bleeding: if it is a sharp instrument stabbing, then the medical examiner can be based on the area of trauma and the amount of blood captured at the scene, as well as the amount of residual blood in the body and the degree of coagulation to judge the 7, the other special way: for example, the victim is being transfused, according to the drop acceleration rate, the amount of the beginning and the termination of the amount of drugs, calculating the time of death, etc. Water Spirit, so that the interpretation of it can be? Also, I will be these not because I'm a forensic pathologist ...... but because I'm writing a detective novel (I'm a courtroom school), so of course I need to know some of this stuff ......
