COLORADO SPRINGS, Colo. — One victim was a self-described “Master of Silly Business,” a bartender at the nightclub. Another was known for a “heavy hand” pouring drinks to friendly patrons and doling out life advice.

Family and friends of victims of the deadly mass shooting at an LGBTQ nightclub in Colorado Springs, Colorado, began to identify and mourn loved ones lost in the tragedy. Authorities on Monday confirmed the names of the five people killed when a gunman opened fire at Club Q just before midnight Saturday.

During a news conference on Monday, Colorado Springs Police Chief Adrian Vasquez said “often we lose track of the victims” and that they “don’t get the dignity and respect they deserve.”

“We will seek justice for all the victims and honor the community members who lost a loved one,” Vasquez added.

Colorado Springs Mayor John Suthers also expressed his “heartfelt condolences” during the news conference and promised his “unwavering support to the victims, their families, and the LGBTQ+ family.”

Here’s what we know about the victims:

Daniel Davis Aston, 28

Aston was identified by his mother in an interview with The Associated Press. Sabrina Aston said her son, 28,  grew up in Tulsa, Oklahoma, and moved to Colorado Springs two years ago. 

Aston, a transgender man, was a well-known bartender and entertainer at Club Q, the site of the massacre. “It’s just a nightmare that you can’t wake up from,” Sabrina Aston said.

His mother told a reporter he had a penchant for entertaining at a young age. He attended Northeastern State University in Tahlequah, Oklahoma, and became president of its LGBTQ club.

“We are in shock, we cried for a little bit, but then you go through this phase where you are just kind of numb, and I’m sure it will hit us again,” she said. “I keep thinking it’s a mistake, they made a mistake, and that he is really alive.”

Rump was a bartender at Club Q. His Facebook account listed attending Kutztown Area Senior High School in his native Berks County, Pennsylvania. 

Anthony Jaramillo, a friend of Rump, told CBS News he was a staple at the bar and often visited friends home in Pennsylvania. 

“Loving, supportive, with a heavy hand in his drink pouring, and just a really good listener and would not be afraid to tell you when you were wrong instead of telling you what you wanted to hear and that was really valuable,” Jaramillo said.

Aaron Ward, a neighbor of Rump, heard news of his death on Monday morning. As Rump often worked late shifts at Club Q, Ward had few interactions with Rump but remembers him for his kindness.

“I was worried because I hadn’t seen his car in two days,” Ward said. “Someone came over a couple days ago and said they found his phone at the club and they couldn’t find him anywhere… Any time I talked to him or saw him, he was always very nice, very kind, very respectful. What little I knew of him, he was a great guy.”

Last week, Natalee Bingham celebrated Kelly Loving’s 40th birthday at her Denver home with a small cake and a few close friends. For Bingham, 25 and transgender, it was a big deal to celebrate another trans woman’s 40th birthday – many of her transgender friends had died young, she said.

Reaching 40 felt like a milestone.

“It gives us hope we could live a long time,” Bingham said. “It gave me hope that we could live a long, normal life.”
