“Throughout history, it has been the inaction of those who could have acted; the indifference of those who should have known better; the silence of the voice of justice when it mattered most; that has made it possible for evil to triumph.” -Haile Selassie

Law Enforcement Background

With 22 years of experience, I was employed by the Pennsylvania State Police from 1992 to 2015, retiring at the position of Corporal. Working primarily in criminal investigation, I specialized in homicide investigation, cold case homicide investigation, child abduction, child abuse and missing persons. My last duty assignment was as the Unit Supervisor of the Pennsylvania State Police Criminal Investigation Assessment Unit. I was responsible for the coordination of a state-wide Criminal Investigation Assessment Unit, specializing in crimes of a violent or serial nature, participating in the investigation and analysis of crime assessments relating to homicides, suspicious and equivocal deaths on a state-wide basis. I was also responsible for coordinating cold case homicide investigations across the Commonwealth of Pennsylvania.

Auditing Experience

Due to my experience with sexual abuse and rape cases, along with my understanding that those who are subject to rape or sexual abuse within our correctional system are just as much victims as those whom are not, I decided to use my experience and knowledge to help create a safe environment for those individuals incarcerated within the walls of correctional facilities and community confinements. I have since become a certified auditor through the Department of Justice for the Prison Rape Elimination Act and conduct audits, as well as provide training and consultation to adult correctional facilities.
