SAN DIEGO (NEWS 8) — A San Diego Sheriff's deputy who was in the crowd during the Route 91 shooting shared her experiences on Monday as events around the country recognized the one-year anniversary of the mass shooting

The San Diego sheriff's department also showcased the new tools it has to deal with an active shooter incident. 

“There was a lot of chaos, a lot of people falling down, running, trampling,” said SD Sheriff’s Detective Kristy Drilling. “So, we were helping people falling in front of us.” 

Drilling was there on Oct. 1, 2017 at the concert in Las Vegas that suddenly became the scene of the deadliest mass shooting by an individual in U.S. history. 

"It's obviously something I'll never forget,” she said. “The worst night of my life.”

Detective Drilling shared her story as the sheriff’s department showcased its newest tools to help deputies do their job more efficiently if there's ever an active shooter incident here. 

"We're given a lot of tools to use, and hopefully we don't have to use them, but it's nice to have them if we need them - I guess I'll put it that way,” said Drilling. “The more tools we have, the better prepared we are if any situation comes up.” 

Rescue sleds - which allow victims to be easily dragged or carried from a scene - will soon be in every deputy's vehicle. 

Deputies are also being issued trauma kits that can be strapped to their utility belt; giving them crucial lifesaving items that include everything from a tourniquet to halo seals that can quickly close off wounds preventing outside air or dirt from coming in. 

“As first responders, it's our job to get there and help the injured,” said Deputy Cleve Willis. “If the injury is significant, grab your trauma kit and go inside, providing treatment, whatever is needed.”  

While the Las Vegas shooting is something Detective Drilling will always remember, she's determined to make sure it doesn't negatively affect the way she lives her life moving forward. 

"I still go to concerts, it hasn't stopped me from doing what I love,” said Drilling. “But I'm more aware of my surroundings.”
