Malathion poisoning was suspected in a case in which the remains were in an advanced stage of decomposition and the presence of malathion was confirmed by analyses of gastric content and body fat.Abstract:
Deaths as a result of organophosphate poisoning are usually detected by analysis of body fluids and tissues for the presence of the toxic agent. These procedures present particular difficulties when performed on remains in an advanced stage of decomposition. Malathion poisoning was suspected in a case in which the remains were in an advanced stage of decomposition and the presence of malathion was confirmed by analyses of gastric content and body fat. Two species of fly larvae, Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart), were present on the remains. A sample of these larvae was analyzed for malathion content. A total of 574 μg of malathion was detected in 0.26 g of pooled larvae, or a level corresponding to 2050 μg/g of larvae. Presence of organophosphates in arthropod larvae has not been documented previously and the analysis of larvae from decomposing remains may prove a useful technique for detection of these toxicants in decomposing remains.read more

Forensic entomology in criminal investigations
E P Catts,M L Goff +1 more
TL;DR: This review focuses on medicolegal forensic entomology, which deals with arthropod involvement in events surrounding felonies, usually violent crimes such as murder, suicide, and rape, but also includes other violations such as physical abuse and contraband trafficking.

Forensic entomology: applications and limitations.
TL;DR: The principles and methods of forensic entomology and the optimal techniques for collecting insect evidence are described and an accurate and convincing presentation of such evidence in court is hampered or even impossible.

Forensic Entomology: An Introduction
TL;DR: The breadth of forensic entomology is studied, including the influence of the environment on specific insect species and its role in post mortem estimation, as well as the techniques used for preserving and mounting insect specimens.

Early post-mortem changes and stages of decomposition in exposed cadavers
TL;DR: Although the process of decomposition is continuous, it is useful to divide this into a series of five stages: Fresh, Bloated, Decay, Postdecay and Skeletal to provide a framework for consideration of the decomposition process and acarine relationships to the body.

TL;DR: An overview is given on sampling procedures for routinely collected specimens as well as on alternative specimens that may provide additional information on the route and timing of exposure to a specific xenobiotic.

Arthropod succession patterns in exposed carrion on the island of O'ahu, Hawaiian Islands, USA.
TL;DR: Differences in species composition at each of the 2 sites and in microhabitats resulted in differences in the duration of stages of decomposition between sites, resulting in variations in arthropod succession patterns in exposed carrion.

TL;DR: Arthropod succession in exposed carrion in a tropical rainforest on the island of O'ahu, Hawaiian Islands, was observed and a total of 45 species in 10 orders, 27 families, and 40 genera was recorded.

Drug identification through analysis of maggots.
TL;DR: The examination of insect larvae from decomposed bodies not only can serve in the estimation of the postmortem interval but also can be used in qualitative identification of drug substances.

Effect of cocaine in tissues on the development rate of Boettcherisca peregrina (Diptera: Sarcophagidae).
TL;DR: Differences observed in the rate of development were sufficient to alter postmortem interval estimates based on larval development in decomposing human tissues by up to 24 h.

TL;DR: A classified checklist of arthropods recovered from exposed remains of both humans and test animals in various stages of decomposition on the island of Oahu and Maui, Hawaiian Islands, is presented.
