Summary
DNA testing is crucial in homicide investigations. This review highlights nine scenarios where DNA evidence aided police, death investigators, and attorneys in solving cases and ensuring justice.
Area of Science:
- Forensic Science
- Molecular Biology
- Criminal Justice
Background:
- The increasing prevalence of DNA testing necessitates awareness of its capabilities among legal and investigative professionals.
- Effective utilization of DNA evidence in homicide cases requires understanding its role from crime scene to courtroom.
Purpose of the Study:
- To review homicide investigation scenarios where DNA evidence was pivotal.
- To identify key educational issues for law enforcement, death investigators, forensic pathologists, and legal professionals regarding DNA evidence.
Main Methods:
- A retrospective observational study analyzing casework from 2000-2014.
- Presentation of nine distinct homicide scenarios involving 11 deaths, detailing investigative and forensic processes.
Main Results:
- DNA testing played a significant role in the successful prosecution of diverse homicide cases.
- Analysis emphasizes the importance of proper sample collection at crime scenes and autopsies for DNA analysis.
Conclusions:
- Case examples demonstrate the value of DNA testing in adjudicating homicides.
- Enhanced understanding of DNA evidence utility can improve investigative and legal strategies.

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
