During the Zombie Crawl on Saturday 9 out of 32 Reno businesses served alcohol to underage volunteers in a Regional Street Enforcement Team alcohol sting. The team contains detectives from the Reno Police Department, Sparks Police Department and the University of Nevada Police Department. The volunteers were two 20-year-old men and two women ages 20 and 19. The Street enforcement team say the costumes they wore did not conceal their identities.
