Characterizing forensically important insect and microbial community colonization patterns in buried remains

Abstract During violent criminal actions in which the perpetrator disposes of the victim’s remains by burial, the analysis of insects and bacterial colonization patterns could be necessary for postmortem interval (PMI) estimation. Our research aimed to assess the decomposition process of buried rat...
