LITTLE ROCK, Ark. — Many lives may have been saved in Saturday morning’s mass shooting at a Little Rock nightclub thanks to new training for the city’s first responders.

In 2015, the Little Rock Police Department, the Little Rock Fire Department, and MEMS started working together to prepare for mass casualty events. Police officers were trained to use triage kits: a small pack with gauze, dressings, and a tourniquet. MEMS officials say these kits got heavy use Saturday morning.

“When paramedics began to arrive on scene… we found that some of the victims had already been triaged by the police department,” said MEMS operations director Greg Thompson, “A total of five tourniquets were used and one chest seal. A few years ago we would have never seen anything like that. I believe that their actions had direct positive impact on the outcome of this.”

Thompson said several victims left the club on their own and went to nearby hospitals. MEMS worked with Arkansas Trauma System to transport ten victims to hospitals.
