Michael Yoder is a retired special agent of the [[Federal Bureau of Investigation]] who spent nearly a decade as a criminal profiler in its [[Behavioral Analysis Unit]].[^1]

At the request of *[[The Philadelphia Inquirer]]* he reviewed the 1985 psychological evaluation of [[R.C. Horsch]] by [[Don Seraydarian]], made for Horsch's federal drug sentencing. He said it was unusual for such an examination to be made in a drug case, that he saw "overwhelming hallmarks of psychopathy" in it, and that it would have been a red flag for criminal profilers: "If you were to give me this report and I knew nothing about this person, and knew nothing about the crimes he committed, I would say you have a potential serial killer on your hands."[^1]
