Quality & Reliability
8/10
The episode features a highly experienced cold-case investigator (Paul Holes) who provides detailed, first-hand accounts of investigative processes, including the use of investigative genetic genealogy in the Golden State Killer case. The discussion is grounded in practical experience and includes specific technical details (e.g., SNP profiling, GEDmatch, Family Tree DNA). However, the information is presented in an interview format without formal citations or peer-reviewed references, and some claims (e.g., about Marilyn Monroe evidence destruction) are based on personal opinion and investigation rather than published sources.
