    Study Notes

    Using Insects and Soil Science to Solve Homicides

    • Police departments around the world work on solving murder and manslaughter cases, but many unreported cases go undetected.

    • Scientists and police investigators are developing new methods, including forensic entomology and soil forensics, to solve more cases.

    • Forensic entomologists like Jens Amend research cadaver colonization by insects to determine time of death and other details.

    • The Institute for Forensic Medicine at Frankfurt University has been investigating unexplained deaths since 1927, and Jens Amend established one of four special departments for forensic entomology in Germany.

    • In Boston, Robin Cotton, an experienced forensic scientist, has testified as an expert witness in over 200 trials and recognizes the usefulness of insects in criminal cases.

    • Insect colonization of a corpse is the best method for determining how long a body has been lying at a crime scene.

    • Insects can also be helpful in determining the cause of death and even the murder weapon.

    • Soil science combined with entomology is being used to convict more murderers, and Lorna Dawson, a professor at the James Hutton Institute in Scotland, has been doing research in soil forensics for over 30 years.

    • The national soil archives of Scotland have been located in the basement of the James Hutton Institute since 1934, containing over 4.8 tons of soil samples from 13,000 different locations in the country.

    • Soil forensics analyze multiple samples of the same case, and the characteristics of those samples can be compared to an unknown sample recovered from a crime scene.

    • In Glasgow, police investigators secured video material from surveillance cameras and identified a suspect in the murder of a 24-year-old student Karen B, whose body was found on a farm field outside of Glasgow.

    • Insect and soil forensics, along with other forensic methods, have helped police departments achieve a 100% detection rate for homicides in Scotland.The Role of Forensic Science in Solving Murders

    • Forensic evidence, including soil and entomology analysis, is a crucial and integral element in solving murder cases.

    • The examination of a potential burial site can provide vital clues in a murder investigation.

    • Accurate scientific findings, such as the identification of insect species, can help find witnesses and leads from the general public.

    • Forensic entomology, the study of insects in relation to criminal investigations, is a young scientific discipline that requires appropriate experience to interpret evidence.

    • Mistakes can happen in handling DNA material, leading to contamination and incorrect expert testimony.

    • In the 19th century, scientists such as Hermann Reinhardt and Jean-Pierre Menaul laid the foundation for forensic entomology, developing theories on insect colonization and decomposition.

    • Modern research focuses on improving the quality of findings through the study of living research subjects.

    • Soil analysis, including the comparison of soil samples, can identify a location by its underlying geology and vegetation, as well as the DNA within the soil.

    • The EU-sponsored mySAFE project aims to continuously improve methods of comparative soil analysis and develop a Europe-wide soil DNA database.

    • The detection rate of violent crimes is increasing thanks to advancements in forensic science, but criminals may adapt to investigative methods, making it harder for investigators to stay ahead.

    • The evidence in cold cases can be stored for many decades and can be re-examined with improved methods.

    • Forensic science is an important tool in giving closure to families of murder victims and bringing criminals to justice.Forensic Entomology: How Insects Help Solve Crimes

    • Insects, particularly flies, are reliable investigative assistants to the police force as they fly to cadavers to lay their eggs and can help determine the time of death.

    • Forensic entomology is an emerging field in Germany, and there is a need for closer collaboration between police investigators and scientists to promote and realize larger research projects on decomposition.

    • Communication is a key issue in improving collaboration between investigators and scientists, where police need to explain their needs to scientists and vice versa.

    • Investigators need to be careful about sharing too much information about the case with the person examining the evidence to avoid potential bias.

    • Pig cadavers are used to study the development of larvae on corpses and are examined using methods that are becoming more sophisticated.

    • Jens Amend, a forensic entomologist, is analyzing the isotope patterns of insects to determine the post-mortem interval and the circumstances of the crime itself.

    • Forensic entomology gained attention in Germany in the late 90s when an ant was used as evidence in the Pastor Geyer case, leading to a conviction for murder.

    • Today, German police routinely consult forensic researchers for advice when determining the time of death of a body.

    • Insect analysis can narrow the post-mortem interval down to a few days and help match suspect statements to the determined time of death.

    • Other research branches of forensics, such as soil analysis and DNA phenotyping, are gaining traction and could make the perfect crime virtually impossible.

    • The personal motivation for scientists like Jens Amend is the fascination of entering uncharted territory in basic research and the practical application of producing data that can be immediately applied to solve crimes.

    • In the future, forensic entomology and other forensic research branches could continue to make significant contributions to solving crimes and making life for criminals even harder.

    Using Insects to Solve Crimes: The Role of Forensic Entomology

    • Insects can be the only witnesses to a crime, and forensic investigators often rely on them to solve cases.

    • In Hawaii, investigators used insects found on a body to determine the time of death of a murder victim. Entomologist Dr. Lee Goff collected and studied the insects to establish when the victim was killed, providing crucial evidence for the prosecution's case.

    • Goff used maggots, which develop on a dead body soon after death, to determine when the victim was killed. By studying the life cycle of the maggots, he was able to estimate the time of death to within a few days.

    • The insects can also provide information about the location of the body and the cause of death. In the Hawaii case, bloodstains found in the victim's house matched her blood type, providing further evidence for the prosecution's case.

    • In Tennessee, investigators used a wasp nest found on a skull to determine the time of death of a young female victim. Forensic anthropologist William Bass used the wasp nest to estimate when the skull had dried out, providing a minimum time since death.

    • Forensic entomologist Neal Haskell was able to confirm the minimum time since death by studying the life cycle of the wasps that built the nest.

    • Insects can also be used to identify victims. Bass was able to determine the age and sex of the victim from the shape and size of the bones.

    • Insects can be affected by environmental factors, such as temperature and humidity, which can impact their life cycle. Investigators must take these factors into account when estimating the time of death.

    • Entomologists use a variety of techniques to collect insects from a crime scene, including nets and tweezers. They also examine soil and other surfaces around the body for insects.

    • Insects can provide valuable evidence in cases where other clues are lacking. In both the Hawaii and Tennessee cases, insects provided crucial evidence that helped to solve the crimes.

    • Forensic entomology is a growing field, and researchers are constantly developing new techniques and methods for using insects to solve crimes.

    • Despite their importance in forensic investigations, insects are not infallible. Investigators must use multiple sources of evidence to build a strong case, and take into account the limitations of insect evidence.The Role of Insects in Death Investigations

    • Insects can provide crucial information in death investigations, such as the estimated time of death and identification of the deceased.

    • Forensic entomology has been around since the 13th century in China, but it has only been widely used in the United States since the 1950s.

    • The field of forensic entomology is not widely studied, and there are only a few dozen insect specialists in the United States who regularly assist with murder cases.

    • Insects, such as flies and beetles, are attracted to decomposing remains and lay their eggs on them, resulting in maggots that can be used to estimate the time of death.

    • The behavior and growth rate of maggots can provide investigators with a good idea of how long a body has been left in the open.

    • In 1987, the skeletal remains of a 15-year-old girl named Michelle Denise Anderson were discovered, and insects helped investigators estimate that she had died at least a year and a half prior.

    • Insects can also act as filters and be tested for chemicals and drugs they may have picked up from their host.

    • In a case in an Indianapolis suburb, the mummified remains of two women were found in a house filled with trash. Insects, such as beetles, provided clues about the time of death.

    • Forensic entomologist Neal Haskell identified the particular insect species that colonized each woman's remains and theorized that the older woman died first in October 1977, while the younger woman likely died in late December 1977 or early January 1978.

    • The man who lived in the house with the women for 10 years after their deaths was never charged, and their deaths were recorded as due to natural causes.

    • Insects can be vocal witnesses to the circumstances of a person's death, and their behavior can provide crucial information for investigators.

    • Despite the cultural prejudice against insects, studying them can provide valuable information for forensic investigations, and anyone who takes the time to learn about insects' behaviors can become interested in them.The Power of Bugs in Forensic Investigations

    • Social Security money was partially paid back by the sale of property that bugs helped detectives solve in the Curious Case of the Indianapolis mummies.

    • Insect specialists like Neal Haskell are using bugs as powerful allies in criminal cases, especially as technology becomes more sophisticated.

    • Bugs, such as mosquitoes, bedbugs, fleas, and lice, are being used to analyze human DNA found in blood meals for forensic investigations.

    • The study of insects is still a field with much to learn, especially in investigating death, according to entomologist Lee Gogh.

    • Forensic entomology needs to be put on a firmer statistical basis and more modeling is necessary.

    • As more scientists enter the field and learn about insect behavior, the value of forensic entomology will continue to grow.

    • Law enforcement agencies were initially skeptical of forensic entomology, but it has become a widely accepted and powerful tool for investigations.

    • Bugs are the smallest witnesses to murder and their contributions are invaluable to homicide investigators.

    • The study of insects is the study of the great tenacity and variety of life.

    • Bugs are becoming increasingly important in criminal cases as technology advances.

    • Bugs, such as mosquitoes, can be used to analyze human DNA found in blood meals.
