Flagstaff resident Jete White, left, 23, blows into a sobriety test administered by Dan Mulleneaux, a Phoenix police officer, during a sobriety certification and testing event at NAU’s du Bois Center on Jan. 10.

The Northern Arizona University Police Department sponsored a three-day workshop to join forces with other law enforcement agencies and Flagstaff downtown bar owners to step up the fight against underage drinking and DUIs.

The third day of the training featured community involvement with volunteers drinking alcohol and being tested by officers.
