Case Studies
A good example of a case where forensic entomology was successful in determining a postmortem interval is one involving a young prostitute and a thirty-year-old member of the Army. A family member had informed the police of her disappearance four days before her body was found. She had last been seen in the presence of this military man on May 31. A large number of adult flies and maggots were noticed and gathered inside and near the wounds of the young girl. A number of these maggots were kept and grown to be adult flies (reared), and others were taken in their present state. Pictures were taken and enlarged showing the flies around the body when it was found. Using this evidence along with correlating weather conditions known to be present around that time, an entomologist was able to give a postmortem interval. The evidence showed that the flies had arrived on May 31, which indicated a time period of four days since she had died. This information showed the army man to be the last person to be with the girl. When presented with the evidence authorities where able to get a confession out of the man. The use of forensic entomology was definitely a key factor in this case.
Another case where forensic entomology was used successfully deals with a body being reported to be thrown down a well. When authorities searched for the well in southern Indiana, it was clear they found the correct one. Thousands of flies where flying over material blocking the well. The pungent smell and the fact that the flies could not access the body created this swarm. Given that vast number of wells in the area, the presence of the flies indicated the body’s presence allowing it to be found in a timely manner. The use of entomology is not only important in determining when a person has died, but also simply locating a corpse.

Famous quotes containing the words case and/or studies:
“In all unmerciful actions, the worst of men pay this compliment at least to humanity, as to endeavour to wear as much of the appearance of it, as the case will well let them.”
—Laurence Sterne (1713–1768)
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
