Friends of Diane Hollick gather after her sudden death for a murder trial that ultimately reveals the killers. DNA evidence clears Diane's fiancee and IBM friend as suspects.
DNA testing in criminal investigations started with the establishment of the FBI's DNA database in 1998, which revolutionized the way DNA was used as evidence. Private companies also started offering DNA testing services, but the discovery that DNA could be extracted from everything someone touched elevated its use to an indispensable tool in solving crimes.
The process of transferring DNA evidence from local authorities to the FBI during criminal investigations is explained. This includes collecting the DNA sample from a loved one, sending it to London and ultimately transferring it to the morgue for analysis.
Investigators couldn’t prove that the substance found at the murder site was Jennifer’s blood as the sample was too small to even match it with a partial DNA profile. They decided to look into a potential lead about Jennifer’s body being taken to a pig farm and devoured by the pigs.
The speaker is skeptical about the reliability of Detective Green's word concerning the 4 a.m. calls made by the person of interest and questions the evidence related to the calls.
