The outpouring of support is extremely strong in Las Vegas as people continue to line up to make blood donations and show their appreciation for law enforcement who are still working the scene — two days later.
People waited in line for hours on Tuesday outside of blood donation centers.
"I wanted to be part of the community response and help the victims of the shooting," Doug Laidlaw said.
Some people spent their day off donating blood while others brought their coworkers to donate, saying it was the least they can do after the unimaginable tragedy.
Sarah Huff said she was donating because her friends were at the country music festival where a gunman opened fire on concert goers from the 32nd floor of the Mandalay Bay Hotel and Casino on Sunday.
Fifty-eight people were killed. The gunman was found dead when the SWAT team arrived at his hotel room.
One of Huff's friends was among the more 500 people injured by the gunfire.
"She actually got out. She got shot in the shoulder. It broke her bone," said Huff.
For those in Las Vegas' hospitality industry, donating means doing what they do best.
"When you hear the heroics that people laid down their lives for those that couldn't, it makes you want to do your part, pitch in," said Garner McCray, who donated blood.
Back out on the Las Vegas strip, people who had attended Sunday's concert were still in the area, replaying the horrific tragedy.
Chynna Curflueh was still wearing her wristband Tuesday from the Route 91 Harvest Festival, which took place across the street from the Mandalay Bay.
"Just to remember the thing that happened and how people were so heroic in my hometown," she said.
Curflueh said during the shooting, she looked up and saw flashes of light coming from two rooms of the hotel. She and her friends had thought there were multiple shooters. That's when they ran, at times ducking for cover.
"It was tough when we were laying on the ground, there were bullets. From the angle they were being shot they were hitting the ground in front of us... That was the toughest part," Curflueh said.
She said heroes saved her life as she crouched on the ground, bullets whizzing by her head.
"The person who covered me was such a blessing,"Curflueh said.
She also saw people head towards the danger.
"Carrying people who had been hit, unable to move," Curflueh recalled.
Curflueh, who is studying to be a nurse, said it was incredible to see the heroism on that horrific night. She says she hopes someday that she too will be that brave when faced with a crisis.
