Dozens of vigils were being held across the country. By early Monday, more than $1.3 million had been raised by a local LGBT group, Equality Florida, for victims and their families.

Friends and relatives were still struggling to make sense of what happened.

"Completely in shock," a friend of Almodovar's wrote on his Facebook page. "I can't believe you are one of the victims."

Another recalled how Almodovar always "[b]rought a smile to my face every time I was down. It's going to be hard walking into work and not seeing you bounce around like you always do."

Stanley Almodovar III, Luis Vielma, Luis Omar Ocasio-Capo, Kimberly Morris, Edward Sotomayor Jr.

David Sotomayor, Edward Sotomayor's cousin, put it this way. "You never think that's going to be the last time you speak to him," he told The Associated Press. "It's just heartbreaking to know it just can happen any time."

Jennifer Eastman, who used to work with Morris, called her friend "an amazing woman."

"She didn't live her life according to anyone's guidelines," Morris told NBC News. "She was simply Kimberly. And she expected you to treat her as such."

Some relatives were still awaiting news.

Felipe "Tony" Marrero, a ride attendant at Universal Studios, was shot several times and remained in critical condition, his family told NBC News.

Marrero's friend and colleague Luis Vielma is on Orlando's list of fatalities. A photo of the pair with several friends was posted on Vielma's Facebook page Saturday under the caption: "True friends who become family."

Vielma was an emergency medical services student at Seminole State College, according to a statement from the school.

He was taking summer CPR classes at Seminole and also reportedly worked on the "Harry Potter" ride at Universal Studios. J.K. Rowling, who wrote the novels, tweeted that she "can't stop crying."

Marrero's mother, Jacqueline Perez, told NBC News she grieved for Vielma's family but was overjoyed when she learned that her son had survived.

"I was so relieved," she said. "It's like seeing your baby all over again."

Perez said she'd been expecting bad news, "because Tony is not the type of person never to contact me or not keep in contact."

Another woman who suffered six gunshot wounds, Marissa Delgado, lost a lot of blood and wasn't doing well, a relative who did not wish to be identified told NBC New York. The relative asked that people pray for Delgado.

One woman, Mina Justice, recalled how her son, Eddie, sent her a flurry of panicked texts from the club's bathroom in the middle of the night.

"He's coming," he wrote, according to the AP. "I'm gonna die."

A few minutes later, after Justice had called the police, she asked whether he was in the bathroom, according to the AP. "Yes," he responded.

It was the last thing Eddie wrote. The city of Orlando confirmed late Sunday that he was among the dead.
