my findings. Following the forensic identification people to the body, we move along the
"path of contamination" which is the route police use to minimize chances of
trampling evidence at the scene (this is the approach least likely to have been taken by
the perpetrator). The body is an adult male lying face down, head through the bottom of
rusted wire fencing and shrubbery.
"I need access to the head, that's where blow flies usually first
lay eggs" I say. The forensics snip wire and vegetation from around the head. I set
to work sampling for insect larvae, taking the temperature of each collecting site first.
I take samples of larvae and place them on bite-sized pieces of raw beef liver,
effectively initiating rearing procedure.
About one-half of the larvae will be reared to adult flies. I plunge
several larvae from each sample into scalding water for a few minutes, then transfer the
specimens into 80% ethanol. By killing some of the maggots I have effectively frozen the
moment in time. "Is this a bullet hole?" I inquire. Sure
enough. The coroner has already been to the scene and pronounced the death, but forensics
needed time to work the scene before body removal and autopsy which I will also attend.
Suddenly, there is a flurry of activity as they photograph anew the body. I stand aside,
my own work temporarily placed on hold. |

Forensic investigation is hardly an unknown field to
the insurance industry. However, an area that seems to garner little attention in claim
investigation procedures is forensic entomology - which could save insurers and insureds
millions of dollars. Bug investigations? You have to be kidding. But, as the following
case study reveals, insects can reveal many secrets in the process of claims
investigation. |

Forensics reports to the
command post. The suspicious death is now officially a homicide. Before leaving the crime
scene in order to follow up sampling during the autopsy, I confirm that forensics
have installed a temperature "datalogger" at the crime scene. |

There is a suspicious death: human remains are
discovered on the edge of a wood bordering a meadow. A municipal crew came across the
corpse while collecting garbage. Police observed fly larvae (maggots)
associated with the |
decomposing remains. The forensic identifier at the scene
telephones me. I arrive at the police command post and before anyone can comment, I say
"no thanks, I don't want to know when you think he died". I need to remain

The unit will continue to
record crime scene temperature for the next week or so. Later, I will download this
"climatological data" into my computer to
