It is difficult to estimate PMI of whom died long times ago, because corpse goes by many decomposition stages. So it makes investigation more difficult. Nowadays many studies about PMI estimation have been performed. In other countries, forensic entomology studies which is possible to estimate not characteristic of death site but also exact death time are actively advanced. So forensic entomology has been more important related not PMI estimation but also many lawsuits in other countries. In Korea, the necessity of Forensic entomology has increased after occuring of the case 'Gaeguri Sonyeon(missing boys who went to catch a flog)'. In this case, regional characteristic is known by insects found on the corpse or clothes. We suggest possibility of applying forensic entomology, consideration, some limitations and the direction of the future study through the analysis, comparison with true facts, and PMI estimation using collected fly larvae in "Hwaseong Case".

Forensic entomology provides a feasible way to estimate postmortem interval (PMI), of which the growth and development of sarcosaprophagous insects is the most widely used indicator in forensic practice. Over the years, forensic entomologists have carried out a large number of studies on the development biology of sarcosaprophagous insects. This paper illustrates the main factors that affect the development of sarcosaprophagous insects, including temperature, humidity, light, food types and poisons. The development indicators of sarcosaprophagous insects were reviewed from the perspectives of morphology, differential gene expression and biochemical characteristics. It is emphasized that future research of development biology on sarcosaprophagous insects should fully absorb and integrate the methods of artificial intelligence and omics, and the research object also needs further expansion in order to establish a more objective and more accurate PMI estimation method.

It is a difficult problem of forensic medicine to accurately estimate the post-mortem interval. Entomological approach has been regarded as an effective way to estimate the post-mortem interval. The developmental biology of carrion-breeding flies has an important position at the post-mortem interval estimation. Phorid flies are tiny and occur as the main or even the only insect evidence in relatively enclosed environments. This paper reviews the research progress of carrion-breeding phorid flies for estimating post-mortem interval in forensic medicine which includes their roles, species identification and age determination of immatures.

OBJECTIVES: To explore the number of necrophagous flies and seasonal distribution of common necrophagous flies at present in Beijing. METHODS: The specimens of necrophagous flies were collected by the methods of animal carcass, trapping and feeding. And the specimens were observed and counted after the classification and preservation. RESULTS: The necrophagous flies in Beijing belonged to 4 families, 9 subfamilies, 21 genera and 46 species, and 12 species of them were the first records in Beijing. The necrophagous flies had the characteristics of regional and seasonal distribution. CONCLUSIONS The data of seasonal distribution of necrophagous flies and common necrophagous flies in Beijing can provide reference for related research.

Postmortem interval （PMI） estimation is a major problem in forensic medicine and a vital indicator of crime investigations. Forensic entomology provides a new way to the PMI estimation, and its superiority has been confirmed through many cases, especially in relation to the cadaver at the stage of advanced decomposition even skeleton. The technologies of forensic entomology have become more mature. This review describes the mechanism of forensic entomology used for PMI estimation, emphasizes the standardized application of technology, and lists the data for the reference of forensic experts in China.

Estimation of postmortem interval （PMI） has always been one of the difficult problems for forensic scientists. It is especially hard to estimate the PMI of highly decomposed corpses in the wild or in secluded houses with conventional methods. Therefore, application of insect evidence at the scene is usually required for estimation. Sarcosaprophagous flies of different species have totally different developmental rates. In actual cases, direct measurement of the body length of the larvae, calculation of accumulated temperature and succession stages without species identification, or calculation based on incorrect species identification would often lead to a large deviation between the calculated results and the real PMI. This mistake would also mislead the case investigation. Therefore, accurate species identification should be implemented before any PMI estimation of decomposed corpses with forensic entomological methods. This article reviews the general and ultramicroscopic species identification and molecular biological species identification methods of different stages of sarcosaprophagous flies, in order to provide new ideas and methods for related research and practice, and provide reference for the application and promotion of forensic entomology in the front line of public security.
