Every criminal has multiple motives, though one may predominate in any particular case.

For assassins, two motives predominate: grievance and performance.

Grievance is a broad category, encompassing all manner of extremism, personal and political grudges, and anything else stoking anger.

Over the past 30 years, Stephanie Erickson, LCSW, has developed expertise in objectively evaluating situations in which abuse or neglect allegations are made about a vulnerable person and presenting her findings to the court to demonstrate the relationship, if any, between the alleged abuse or neglect and the vulnerable person's ability to function. The vulnerable individuals with whom she has extensive experience include children, adults, and older adults, many of whom have a mental illness, physical illness, dementia, or a developmental disability. These evaluations often require assessment of not only the vulnerable individual, but also family dynamics, caregivers, and healthcare organizations, such as nursing homes, board & care homes, assisted care homes, or the child welfare system.

Dr. April Gould is an expert on radicalization, extremism, and collective violence. This expertise derives from both her academic research and her personal experience interviewing and analyzing hard-to-reach and violent criminal populations. She is qualified to testify as an expert in cases in which individuals have been radicalized online or through group involvement and have acted on behalf of personal or collective grievances, and she would be effective in investigating, locating, and interviewing people who would prefer to remain off the grid.

Three Common Errors Lawyers Make in Retaining Experts

Park Dietz, MD, MPH, PhD

Since 1996, when PD&A began operation as a formal group, lawyers have inquired about many thousands of new cases, both civil and criminal. I’ve spoken directly to all of those who didn’t already know which experts they wanted to retain. While most of these lawyers were sophisticated about the use of experts, a surprising number seemed naïve about how to evaluate the fit between expert and case, how to judge hourly rates, and when they should retain. I share here some of the common errors lawyers make in seeking experts.

World-renowned forensic psychiatrist, Dr. Park Dietz, who has testified and consulted on well over 20 serial killers, shares details about Jeffrey Dahmer, a criminal defendant in whose trial he testified.

Dr. Shawnté Alexander is a child welfare, investigations, and standard of care expert with a doctorate in Counseling Psychology. Dr. Alexander’s career and expertise span over 20 years working in sexual abuse prevention and response, child protection investigations, forensic interviewing, case management, and foster care.

Dr. Heilbrun has been involved in personally conducting or supervising approximately 3,100 forensic evaluations at the request of courts, defense, and prosecution, and has testified as an expert approximately 310 times at the request of both the defense and the prosecution.

Ray Mey’s extensive background in all aspects of physical security have proved invaluable to law firms representing plaintiffs and defendants in cases regarding event venues, commercial properties, and residential properties in civil actions alleging negligent security.

Commercial and residential properties such as event venues, apartment complexes, hotels, bars, restaurants, parking lots, hospitals, and other businesses owe a duty of care to their residents and patrons. Safety and security are critical elements of duty of care.

Dr. Newman has both clinical and forensic experience in psychopharmacology, violence risk assessment, malingering, criminal and civil competencies, criminal responsibility, involuntary administration of medications (including Sell hearings), and conditional release assessments.
