Boulder Police on Tuesday released a sketch of a second suspect in a violent robbery that occurred shortly before 7 a.m. on Thursday in the 800 block of Circle Drive.

Two men are suspected of approaching a 56-year-old woman who was loading a car parked in her driveway. One of the men hit the woman in the face and made off with a black suitcase full of medical supplies.

The suitcase is described as a black, nylon carry-on size Victorinox suitcase on wheels. The luggage contains a red cross similar to that found on Swiss Army knives.

One suspect was described as a white male in his early 20s, about 5-feet, 8-inches tall and 165 pounds. He had dark-colored sideburns and was wearing dark clothing and a dark ball cap. The second suspect was described as a Hispanic male in his early 20s, about 5-feet, 6-inches tall and 145 pounds. He was wearing dark clothing and a dark ball cap. He also had small hoop earrings, one in each ear.
