Please trust that Dr. Harrington will let you know if there is a case that may be outside of his scope of practice. A case that may only require an attorney, or is simply something that may not benefit from conducting an intensive, thorough investigation. 


Most of the cases that Dr. Harrington receives, involve allegations of violent crime (e.g. murder, rape, assault, robbery, etc.) and will be investigated at the direction of the Client's attorney. Dr. Harrington will work diligently, as they gather the relevant facts and supporting documentation with the aim of assisting your attorney.
