In this illuminating episode, hosts Kalen and Karen shine a spotlight on Alternate Light Source (ALS) technology—a very powerful tool in the forensic nurse’s toolkit for revealing hidden injuries, especially on darker skin tones.
Our expert guest, Dr. Katherine Scafide, PhD, RN, FAAN, FAAFS—a tenured Associate Professor (George Mason University) and renowned forensic nurse scientist, also known as “the paintball lady”—joins us to break down the science behind ALS, share actionable insights from her groundbreaking research and discuss the ethical implications, limitations, and future directions for ALS in both clinical practice and in the courtroom. Grab your goggles and let’s go beyond the visible!
