Self-Identified Vampirism and Risk for False Positives: A Case Example of Team Homicide and Implications for Forensic Behavioral Science.

Historically, reported cases of self-identified vampirism typically have been associated with psychopathology and sometimes a propensity for violence. However, scholars recently have noted a wide range of diverse practices and meanings that all fall under the general description of self-identified vampirism. This brief report focuses on a homicide case (male and female partnered offenders), wherein a single victim was murdered and dismembered. Due to specific case evidence, there was controversy regarding whether or not the homicide was motivated by ritualistic self-identified vampirism. Court documents were reviewed and assessed, and findings suggest that the evidence used to support assertions that homicidal motivations occurred due to ritualistic vampirism was misinterpreted due to the omission of a growing multidisciplinary literature on self-identified vampirism. It is important for forensic experts to be aware of emerging research on alternative identities, including vampirism, that challenge traditional theories and assumptions.
