New research could help nurses, police detect bruises² on people with dark skin

Transcript³

For many cases of assault and domestic violence, investigations⁴ begin with a search for proof. But for victims with darker skin, it can be hard for nurses and police to detect bruises.

That difficulty can stymie⁵ the care and the justice these survivors⁶ receive. But now, new research is trying to make that process more rigorous and effective.

Katherine Scafide, an associate professor at George Mason University, worked as a forensic⁷ nurse for eight years. During that time, she noticed something about survivors of sexual assault and domestic violence with black or brown skin: it was hard to see their injuries.

Those medical records often become evidence for criminal investigators⁸.

"Bruises tell us a lot about what has happened to a particular patient who's experienced violence and unfortunately if I can't see the bruise¹ clearly it really limits my ability of what to document and what to report in the medical record," Scafide said.

Scafide and her team at GMU found that blue or purple light is as much as five times better at detecting bruises on those patients.

The Justice Department praised the work as a model of inclusive research.

"I think this speaks to the embedded⁹ racial disparities in a lot of the research we do to date, that all of these methodologies that were so traditional were developed to identify bruises on white skin," said Nancy La Vigne, director of the National Institute of Justice, which funded the study.

The research continues. Scafide is now developing a set of guidelines for forensic nurses on using blue or purple light to detect bruises. That's of special interest to Nancy Downing, an associate professor at the Center for Excellence¹⁰ in Forensic Nursing at Texas A & M University.

"It's really important to me that we are not promoting something to be used without people understanding how to use it correctly," Downing said.

Juries want to see evidence of injuries. But there need to be scientifically validated¹¹ standards for using these technologies to help prevent wrongful convictions.

Chris Fabricant, a lawyer at the Innocence¹² Project, agreed.

"The use on the front end of unreliable or untested forensic evidence to secure convictions makes it really almost impossible to undo¹³ miscarriages¹⁴ of justice unless you have conclusive¹⁵ DNA¹⁶," Fabricant said.

DNA is often not available at crime scenes, despite its prominence¹⁷ in the popular culture, which makes it all the more important to develop objective standards for evaluating bruises, he said.
