Forensic anthropology - arcl sept 26 - estimating time since death postmortem interval (pmi) time since death (tsd) forensic taphonomy: what happens to the body after death stages of decomposition. Blu-ish colour of death c. i. c. ii. blood pooling to the lowest part of the body c. iii. Stiffness of death d. i. d. ii. stops producing atp - muscles - causes the stiffening d. iii. stiffening of arrector pili (starts small one) d. iv. 3 hours -12 hours d. v. environmental factors come into play as well, level of physical activity before death, lots of exercise lots of atp happens faster: early decomposition, autolysis = self-digestion a. i. Destruction of cells by the body"s own enzymes a. ii. Occurs in the pancreas and stomach: putrefaction = bloat b. i. 4 to 10 days after death b. ii. colour changes, green + purple b. iii. marbling (blood vessels + bacteria will reach all the soft tissue)
