Episode Details

These sources detail the investigative breakthrough and subsequent arrest of Andrew Dykes for the 1997 murder of Tanya Denise Jackson, a victim previously known only by the nickname “Peaches.” For decades, the case remained an unidentified mystery frequently associated with the Gilgo Beach serial killings until forensic genetic genealogy and a child's birth certificate finally established the victims' identities. Prosecutors allege that Dykes, a former military instructor with specialized knowledge of human anatomy, killed Jackson and her toddler daughter before disposing of their remains in two separate Long Island locations. The narrative highlights how modern DNA technology, specifically evidence recovered from a discarded drinking straw, allowed authorities to link the suspect to the crime scene decades later. Although Dykes has pleaded not guilty, his apprehension marks a pivotal shift in a long-standing cold case by separating it from other notorious investigations and providing accountability for the victims.
