Common Forensic Findings.
Examination of the product is one of the fundamental considerations of product
tampering. There may be visible signs of tampering, such as clearly discolored
capsules. The type of analysis done on the product and victim will depend on
the instrument of death.
Suspicion of
poisoning requires toxicological and chemical analysis of the product and
victim to determine if products of the same lot were in- volved. Because
toxicological analysis is not routine in postmortem examination, exhumation of the
victim may be necessary to detect poisoning. This, along with the distribution
of victims, will help decide if the source of tampering is at the retail or
manufacturer level. Type of poison and consistent or varying levels of poison
in each tainted product reflect the resources and sophistication of the
offender. The packaging of the product will also be revealing of offender sophistication:
this includes absence or presence of fingerprints, repackaging, and the
appearance of the tainted items.
The analysis of
offender communication would be approached in the same manner as in kidnap
murders (see classification 104). If the communication is verbal, a verbatim set
of the caller’s comments and information about speech patterns and accent are
vital to threat assessment.
