Fases de decomposição de carcaças de porcos (Sus scrofa L.) submersas em uma barragem na Amazônia Central

Abstract

The decomposition and fauna colonization on carcasses in the terrestrial environment have been well studied, but knowledge of the process of decomposition in water is still scarce. This article aims to describe the stages of decomposition ten pig carcasses were deployed in a dam in the city of Manaus, in order to increase the accuracy in estimating the postmortem submersion interval (IPMS) for bodies recovered in the aquatic environment in the region. Decomposition time to skeletal remains was 20 days.Six phases of decomposition were established: submerged fresh, early floating, floating decay, bloated deterioration, floating remains and sunken remains. This data will be valuable in forensic investigations involving submerged bodies, indicating the type of water conditions that the body has been exposed.
