<P> The degree of rigor mortis may be used in forensic pathology, to determine the approximate time of death . A dead body holds its position as rigor mortis sets in . If the body is moved after death, but before rigor mortis begins, forensic techniques such as livor mortis can be applied . If the position in which a body is found does not match the location where it is found (for example, if it is flat on its back with one arm sticking straight up), that could mean someone moved it . </P> <P> Several factors also affect the progression of rigor mortis, and investigators take these into account when estimating the time of death . One such factor is the ambient temperature . When conditions are warm, the onset and pace of rigor mortis are sped up by providing a conducive environment for the metabolic processes that cause decay . Low temperatures, however, slow them down . Therefore, for a person who dies outside in frozen conditions rigor mortis may last several days more than normal, so investigators may have to abandon it as a tool for determining time of death . </P> <Ul> <Li> In Kendrick Lamar's 2011 album Section. 80 there is a song titled Rigamortis in which Lamar references rigor mortis . </Li> <Li> In RuPaul's Drag Race All Stars 2, Alyssa Edwards mistakes rigor mortis for Rigga Morris . </Li> </Ul> <Li> In Kendrick Lamar's 2011 album Section. 80 there is a song titled Rigamortis in which Lamar references rigor mortis . </Li>
