Suspect R is a mysterious and dangerous Sinner. She can shapeshift into someone if she consumes some of their blood. She wears a white dress shirt with rolled-up sleeves to the elbows and a wide V-neck, exposing some cleavage, a black bra, high-waisted black tight pants, black fingerless gloves that go up to her elbows, a large gray trenchcoat around her shoulders, and silvery turquoise jewelry. She has a pair of earrings that glow a shade between blue and green.
