In 2017 the United States experienced the largest mass casualty incident in US history when a lone gunman opened fire on the Route 91 Harvest Music Festival taking place on the Las Vegas strip. 58 people were killed and 422 were injured. There were 22,000 people at the event, impacted psychologically by the experience. Clark County requested Courthouse Dogs send 8 dog/handler teams to Las Vegas to work alongside them and the Office for Victims Assistance from the FBI.
7 dogs/handlers from the United States attended and Kim Gramlich and Caber from Delta Police Victim Services in British Columbia attended. For one week these teams responded to the Las Vegas Convention Centre, local hospitals, community and businesses to provide support to victims and other persons impacted by the event. This was the largest, coordinated, Accredited Facility Dog response to ever take place. The dogs/handlers interacted with thousands of individuals and had a positive impact on those hurting from this devastating incident.
