Erika RamadanErika Ramadan

Erika D. Ramadan began her law enforcement career in 2008 as a federal agent with the United States Border Patrol. While she learned vital skills as an agent, her love for working in the field of forensic science full-time had not been obtained. In 2010, she accepted a position as a forensic specialist in Los Angeles, a position she has held for nine years. During this time she has responded to over 250 major crime scenes, most of which were homicides and deputy/officer involved shootings. She has also completed 100’s of fingerprint comparisons as a latent print examiner and lifted over 1,500 fingerprints at crime scenes. Additionally, she co-led a Major Crime Scene Training Program for several years; this program encompasses teaching a curriculum comprised of lectures, practicums and mock crime scenes to new crime scene investigators. Once the lecture portion of the training concludes, she becomes a “roll-out” trainer and responds to major crime scenes to observe how each trainee processes a scene independently.

Erika received a Master’s of Forensic Science degree with a concentration in Crime Scene Investigation from the George Washington University in 2007. Prior to that, she obtained her Bachelor’s degree in Criminology and Anthropology with a minor in Biology from the University of Miami. She has completed several internal courses offered by her agency as well as external courses offered by other organizations. This continual training allows her to stay relevant in the field of Crime Scene Investigation and the ability to teach the latest techniques available. In 2014, she became certified as a Crime Scene Investigator from the International Association for Identification and successfully passed her recertification in 2018. She stays relevant in the field of forensic science by attending professional conferences and is a member of the International Association for Identification (IAI), the California Homicide Investor’s Association (CHIA), and as a board member of the International Crime Scene Investigator’s Association (ICSIA).
