The perpetrator sent taunting letters to the police and newspapers, claiming he would strike only when specific constellations were not visible in the sky. The investigation spanned multiple years and involved complex forensic techniques, including handwriting analysis, fingerprint recovery using chemical reagents, DNA testing from saliva on an envelope, and advanced ballistics involving tool mark analysis of homemade zip guns. The manhunt eventually culminated in the arrest of Eddie Seda following a hostage situation in Brooklyn. Through a combination of forensic astronomy, codebreaking, and traditional detective work, investigators linked Seda to the series of shootings. The episode details the overwhelming forensic evidence that led to his conviction and sentencing to 2 centuries in prison.

This episode investigates the suspicious death of Michelle Nice and the subsequent investigation into her husband, Jonathan.

In 1995, 14-year-old Jenna Mauser disappeared from her home, only for her body to be discovered days later in a roadside ditch. The investigation initially faced a lack of physical evidence, as there were no DNA samples or signs of a struggle within the home. However, a combination of forensic botany and advanced photogrammetry eventually linked her stepfather, Doug Mauser, to the crime. Investigators utilized plant biology to identify specific yellow star thistle found under the suspect's car that matched the development of plants found near the body. Furthermore, 3D modeling of post-mortem pressure marks on the victim's skin allowed experts to recreate the exact pattern caused by a seat belt buckle and carpet edge in the suspect's vehicle. The episode details the reconstruction of the crime and the forensic breakthroughs that led to a murder conviction.

In 1988, the death of popular Durham High School teacher and coach Russ Steger was initially ruled an accidental shooting.
