AMITYVILLE, N.Y. (CBSNewYork) – The Las Vegas massacre has forever changed thousands of lives – not just those of the victims, but also the many people in their lives.

The Sunday night shooting rampage by 64-year-old Stephen Paddock killed at least 59 people including the gunman and injured hundreds more, some from gunfire and some from the chaos that followed.

Rocio Guillen of Eastvale, California, leaves behind four children — Marcus, 18; Chris 13; Sophia, 1 1/2; and Austin, 1 month.

Son Chris loved it when his mother watched him play football.

“I’m not going to be able to see her in the crowd again, and that was my last memory, of her cheering me on,” he said.

Christopher Roybal was a Navy veteran from Colorado who served four tours of duty in Afghanistan.

“He was a goofball. I mean, he’s just fun loving, full of energy, had an infectious smile, and just, I just had such a fun time anytime I was able to interact with him or come to his club because he had such an impact on the people around him,” said coworker Robert Alexander.

Steven Berger had come to Las Vegas from Minnesota to celebrate his 44th birthday, hairdresser Stacee Etcheber was a mother of two from San Francisco, and Heather Alvarado ran a day care center in Utah.

And then there are the victims who are struggling to recover.

Every time Krystal Legette tries to sleep, she wakes up to the horror she witnessed during the massacre.

“There’s blood all over people, and then there’s thinking I was locked in a bathroom just waiting to die,” she told WCBS 880’s Sophia Hall through her tears.

The nurse from Amityville, Long Island, planned to spend a fun time in Las Vegas for her 36th birthday. She was supposed to take a helicopter ride and found herself in an office building close to where the Route 91 Harvest concert was taking place.

She locked herself in a bathroom with other women. One, however, decided to run back outside to find her boyfriend.

“It’s just crazy. You’ve got to sit there and watch people choose for themselves or run after and find the people they love,” she said.

Legette repeatedly told Hall she was not a hero, but she did help some of the wounded that rushed into the office building for cover, including a woman who was shot.

“She’s like gray. I don’t even know if she made it,” she said.

Meanwhile, 24-year-old law student Kristin Babik spoke from the hospital after she was shot in the back.

“There were people on the other side helping people get over and I was so scared,” Babik said. “They gave me the biggest hug and told me everything is going to be OK.”

Michael Caster, 41, was shot trying to shield his girlfriend from the gunfire.

“I was on the ground and couldn’t move,” he said. “I had no feeling from the waist down.”

Caster’s girlfriend, Tawny Temple, refused to leave his side. She used a table as a gurney and then carried him to a stranger’s car.

“People were telling me, ‘Just leave, they’ll come back for the survivors,’ and I said, ‘I’m not leaving him,’” Temple said.

“Well, I did take a bullet for her, so she was just paying me back,” Caster quipped. “No I don’t know. I might not have made it.”

Late Wednesday, the GoFundMe page for Las Vegas victims and their families was nearing $8.9 million, and it continued to grow.
