Supervisory Special Agent Federal Bureau of Investigation
The search for viable deception detection methods has led to decades of research and has resulted in various approaches to differentiate truthful from deceptive statements. While significant progress has been made in the field of deception, no smoking gun exists. This presentation will examine recent analysis into 911 calls reporting homicides, suicides, and missing child cases and will examine the pitfalls of using available deception methods to evaluate the truthfulness of callers. The presenter will discuss the impacts of stress on perception, behavior, and memory each relates to 911 callers. The presenter will further discuss how the utilization of certain deception detection methods for 911 calls can influence our (mis)interpretation of caller statements and the types of questions we ask in subsequent interviews.
Learning Objectives:
To describe the totality of existing research into 911 calls involving homicides, suicides, and missing children cases.
To examine how this existing research intersects with human perception, behavior, and memory when under stress or traumatic conditions.
To examine the impact of reliance on intuition or the use of flawed deceptive indicators for subsequent interviews with victims, witnesses, and subjects.
