Context
Background
The University of Colorado Anschutz Medical Campus in Aurora is one of the nation's largest academic medical campuses, integrating the CU School of Medicine, CU College of Nursing, College of Pharmacy, Children's Hospital Colorado, and University of Colorado Hospital within a dense footprint west of Interstate 225. On the morning of July 10, 2018, Aurora Police Department officers were searching for a man they believed to be armed near the intersection of North Ursula Street and East 22nd Avenue, adjacent to the campus. 9News reported that all campus buildings went on lockdown as a precaution, and area residents were asked to shelter in place. A CU Alert was sent out to the campus community. The suspect was subsequently taken into custody near a parking structure, and a gun was recovered. During the response, an Aurora police officer unintentionally fired a weapon; CBS Colorado reported that no one was struck. The all-clear stated the campus no longer needed to shelter in place. Police confirmed the incident was not an active shooter situation. The incident illustrates how an armed-person search in streets adjacent to a medical campus routinely triggers a full campus lockdown affecting thousands of medical students, residents, nurses, pharmacists, and hospital employees.
