Freeport's Ricky Fannin was at the Las Vegas concert where a gunman opened fire in deadliest mass shooting in U.S. history.

FREEPORT — A Walton County man said he's safe after being caught in the middle of Sunday night’s mass shooting at a Las Vegas country music concert.

Ricky Fannin, who lives in Freeport, posted on Facebook that he was attending the Jason Aldean concert at the Route 91 Harvest Festival when a lone gunman at the neighboring Mandalay Bay Resort and Casino opened fire from the 32nd floor on the crowd.

Fannin said he was too distraught Monday to speak about the incident, but he agreed to share his Facebook post with the Northwest Florida Daily News about the scene of the shooting:

“Never in a million years would I think I'd witness something like this firsthand. Just sad for all those people that didn’t make it out.

“Me and my friends are so fortunate and blessed because the shooter was firing from our hotel across the street. I thought it was a prank of firecrackers. Then next thing we see is Jason Aldean running off the stage. We knew it was real then.

"Then it was massive chaos. All we could do is duck and lay on the floor. Bullets flying over our heads. People being mowed down.

"The security came to each row and told us to run. In the midst of chaos, I got separated from my friends. I was looking around and they were nowhere to be found, finally the security yelled keep running.

"I must have ran what seemed like forever; climbing over barricades and walls. Got to Hooters Casino and waited there a minute, heard from my friends, next thing they are telling us we need to evacuate again, there's rumored to be multiple shooters.

"I met a nice family and we took off and ended up at another casino miles away. The whole strip near the venue is locked down. Regardless we are safe.

"Don't ever take your life for granted folks. Count your blessings. I have cried and just thanked God we made it.

"I can't wait to get back to the best place on Earth, Walton County and hug my family.”

Sunday night’s shooting was the deadliest mass shooting in U.S. history, according to the Associated Press. As of midday Monday, at least 58 were confirmed dead and more than 500 were injured.
