For many cases of assault and domestic violence, investigations 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 stymie the care and the justice these survivors receive. But now, new research is trying to make that process more rigorous and effective.
