Dating Death: Forensic taphonomy and the postmortem interval
Determining the postmortem interval (PMI) remains one of the most important but challenging factors to establish in a suspicious death investigation. Unfortunately, as time passes current methods lose accuracy and only allow investigators to approximate how long ago death occurred. Bodies interred …

Mechanical Properties Of The Intervertebral Disc As An Estimator Of Postmortem Interval
… are only able to determine time since death (or postmortem interval) up to the first 60 hours. This is based largely on insect activity. Herein, it is proposed to use the degradation of the intervertebral disc (IVD) after death to determine a relationship between the mechanical properties of …

Necrobiome Succession in Muscle Tissue as a Potential Indicator of Postmortem Interval
… necrobiome succession and how it relates to postmortem interval through the use of buccal swab and muscle tissue sampling from the arm (deltoid) and thigh (vastus lateralis). The use of muscle tissue samples is a novel means to study bacterial succession during human decomposition. …

The Postmortem Interval: A Systematic Study of Pig Decomposition in West Central Montana
The postmortem interval (PMI) is an important piece of information used by forensic and criminal investigators to help investigate crimes and other unattended deaths. Time since death estimations assist law enforcement in providing a reference with which to compare a suspects alibi, identify …

TEMPERATURE VARIATION IN MARQUETTE, MICHIGAN, CONCERNING SKELETAL MUSCLE DEGRADATION PATTERNS FOR POSTMORTEM INTERVAL DETERMINATION
<p>Postmortem interval (PMI), or time since death, is regularly estimated in criminal investigations. Biochemistry methods can estimate PMI by analyzing changes in protein breakdown within muscle tissue. Observing protein degradation has been proposed as a new method of PMI estimation due to …

The role of struvite crystals and the necrobiome in estimating the postmortem interval for forensic investigations in the UK
… potential preliminary method for estimating the postmortem interval (PMI). The aim of this research was to investigate the use of struvite crystals and the microbial communities that precipitate them in estimating the PMI for forensic investigations in the UK. An in vitro model was established …

USING THE FREEZE-THAW CYCLE TO DETERMINE THE POSTMORTEM INTERVAL: AN ASSESSMENT OF PIG DECOMPOSITION IN WEST CENTRAL MONTANA
… how long an individual has been deceased. The postmortem interval represents the time that has passed since the death of the individual. Understanding how a body will decompose is crucial to estimating the postmortem interval. Extensive research investigating human decomposition patterns has …

Microbial succession in human rib skeletal remains and fly-human microbial transfer during decomposition
… can be used as a forensic tool for estimating postmortem interval. Chapter 1 introduces this concept by describing the stages of decomposition in detail and how high-throughput sequencing methods can be used with microbes to develop models for predicting postmortem interval. Chapter 1 also …

Calliphorid Hygrosensation Perception and the Effect of Humidity on Oviposition Behavior
… environmental conditions to estimate the postmortem interval. However, the accuracy of these estimates can be affected by the time between death and insect colonization, the pre-appearance interval. In cases where insect evidence is absent, it is often unclear whether colonization has yet …

The effect of clothing on decomposition and scavenging in two forensically significant habitats in Cape Town, South Africa
… death investigation involves estimating the postmortem interval, which is influenced by biogeographic factors specific to the region. To ensure the collection of forensically relevant data, the experimental design incorporated single, clothed individuals, as they constitute the majority of …
