What I have described as murky, the neither fish nor fowl nature of the Cold Case Posse, has become more murky with the discovery of a 2012 training manual from the Maricopa County Sheriff’s Office. The manual states:
Maricopa County Sheriff’s Office training provides clear direction to ensure all employees lawfully, effectively, and ethically carry out their duties as deputies, detention officers, civilians and posse volunteers.
One might infer from other language in the document (e.g. Page 13) that the Posses are considered “uncompensated law enforcement personnel” by the Sheriff’s Office.
