Story highlights

Amid the chaos, some relatives and friends watched as their loved ones perished

"I was just yelling at him not to go," one man said, recalling his friend's final moments

(CNN) —  

Tony Burditus never got a chance to say good-bye to his high school sweetheart.

The couple, from West Virginia, had gone to Las Vegas for a weekend getaway – and to attend the Route 91 Harvest music festival. They’d dined out and swum in a gleaming hotel pool, documenting their adventures on social media.

Just before the concert Sunday night, Denise Burditus grinned as she leaned in for a selfie with her husband of 32 years.

It would be one of their last photos together. Within hours, she’d be among 58 victims felled by a gunman in the deadliest mass shooting in modern US history.

Now, Tony Burditus finds himself among survivors of the Las Vegas massacre who share a distinctive grief: they watched helplessly as their loved ones perished amid the barrage of gunfire.

’She died in my arms’

Like most people at the country music concert, Tony and Denise Burditus first thought the rapid staccato that erupted during the show was fireworks.

They just kept dancing.

“She asked me if it was gunfire, I told her, ‘No,’” Tony Burditus told CNN’s Anderson Cooper. “It was during the second burst that we knew – and started … trying to get out of there.”

Even then, the couple didn’t realize the killer had opened fire from a hotel room 32 floors above them.

Had he known, Tony Burditus said, they might have taken a different route.

“I was leading her through the crowd. I initially thought it was an attack from the ground,” he said. “I looked up and didn’t see anything.”

When a bullet hit his wife, a stranger helped move her to a safe spot, away from where others were dropping to the ground. Someone else rode with them to the hospital in the back of a truck.

All the while, Denise Burditus – a retired banking professional who’d just gone back to college – lay silently.

“She was unconscious from the time she was struck,” her husband said.

About seven hours after his wife posted the pre-concert photo as her profile picture, Tony Burditus updated his own Facebook status.

“It saddens me to say that I lost my wife of 32 years, a mother of two, soon to be grandmother of five …. in the Las Vegas shooting,” he wrote. “Denise passed in my arms. I LOVE YOU BABE.”

Burditus planned to stay in Last Vegas until his wife’s remains could be transported back to West Virginia. In the early hours of his sorrow, he’d experienced moments when he couldn’t believe she was gone, he said, and had flipped through his phone and tablet, glimpsing photos of her beaming grin.

“Denise always had a smile on her face,” he said. “And Denise never met a stranger.”

’I hope he heard me’

Sonny Melton had gone to the concert with his wife, Heather.

When the gunfire exploded, the registered nurse from Tennessee quickly tried to steer her away from the mayhem.

“I started feeling the ricochet of the bullets on the ground,” Heather Melton recalled. “And I said to Sonny, ‘Let’s get down.’ And he said, ‘We can’t get down, we’ll get trampled.’”

(CNN) -- In the early days of the investigation into the Las Vegas mass shooting, two people were named as persons of interest in the case, according to newly released police search warrants. One was deceased shooter Stephen Paddock's girlfriend, Marilou Danley, who has since been publicly cleared in the case. The name of the other was redacted in hundreds of pages of documents released Tuesday to the media. The Las Vegas Review-Journal has identified that individual as Douglas Haig. Haig did not respond to phone calls Tuesday evening.
