  • How did forensic scientists contribute to solving cases?

    Forensic scientists played a crucial role in cases with no witnesses by analyzing evidence like bloodstains, cat hair, and shoe prints to link suspects to crime scenes. Their expertise in matching fibers, adhesive, and DNA helped reconstruct the final moments of victims and identify perpetrators, leading to arrests and convictions in murder investigations.

  • What led to the arrest of Dr. Boyle for Noreen's murder?

    Dr. Boyle's suspicious behavior, including his interest in building a playroom in a Pennsylvania house's concrete basement, raised suspicions. Credit card statements revealed purchases of incriminating items like a jackhammer and concrete, aligning with evidence found in a makeshift grave under concrete in his home containing Noreen's remains. Analysis of concrete samples from Ohio and Pennsylvania linked him to the crime scene, resulting in his arrest and conviction for aggravated murder and abuse of a corpse.
