Yowler was recovering from surgery after she was shot in the knee at the theater. Her 32-year-old brother, Nick Yowler, who also shielded his sister, was not injured.
McQuinn and Yowler moved to Colorado from Ohio last fall. A Colorado co-worker told the Springfield News-Sun that McQuinn and Samantha Yowler worked with her at Target.
"They're really fun people. We always go out together," said Melissa Downen.
The death of 23-year-old Micayla Medek was heartbreaking, said her father's cousin, Anita Busch.
But Busch said the news also was a relief for the family after an agonizing day of waiting.
"I hope this evil act ... doesn't shake people's faith in God," she said.
Micayla Medek lived in the Denver suburb of Westminster, Colo., and attended Aurora Community College.
Her aunt, Jenny Zakovich, 57, of South Milwaukee, Wis., said Medek and her father were both huge Green Bay Packers fans.
The youngest of the victims killed in the attack was Veronica Moser-Sullivan.
She had just learned to swim, and at age 6, she was a "great little girl, excited about life," her great-aunt Annie Dalton said. "She should be at 6 years old."
Her mother, Ashley Moser, remains hospitalized with gunshot wounds to her neck and abdomen. She has been in and out of consciousness and asking for her daughter during moments of lucidity.
"Nobody can tell her about it," Dalton said. "She is in critical condition, but all she's asking about is her daughter."
Alex Sullivan's family called him "their real life super hero," and he was at "The Dark Knight Rises" premiere celebrating his 27th birthday and his first wedding anniversary.
"Alex was a gentle giant, known and loved by so many. He always had a glowing smile on his face and he made friends with everyone. Alex enjoyed all sorts of movies, was an avid comic book geek and loved the New York Mets," the family said in a statement.
Sullivan had a warm smile and an innocence that endeared him to people, said Shelly Fradkin, whose son Brian was good friends with Sullivan.
She sat next to a makeshift memorial Friday near the theater where an oversized birthday card with a photo of a smiling Sullivan was displayed.
"He's amazing. He was just a big teddy bear. Great hugs," she said.
She said Sullivan was such a big movie fan that he took jobs at theaters just to see movies.
Fradkin and her son spent an "excruciating" day trying to find Sullivan before learning of his death, she said.
"We're shocked. We're numb. We're sick," she said. "Our hearts are broken, and we're crushed."
Alexander C. Teves, 24, of Phoenix, earned a master's degree in counseling psychology in June from University of Denver.
He was a lovable person who made friends quickly and had a lot of them, said his grandfather, Carlo Iacovelli of Barnegat, N.J.
As a boy, Teves moved from New Jersey to Phoenix with his parents. Iacovelli and his wife wintered there and spent a lot of time with him.
"He was what you might call an ideal grandson," Iacovelli said. "He was a fun guy. He loved to eat."
Teves was planning to become a psychiatrist, his grandfather said.
"He had a lot to look forward to," Iacovelli said.
Rebecca Ann Wingo had started a job several months ago as a customer relations representative at a mobile medical imaging company. She was 32.
Shannon Dominguez, who worked with Wingo on weekends, said she was friendly with everyone and always seemed to be in a good mood.
"I didn't really know her well but she had a really bubbly personality," Dominguez said. "She was a pretty happy person. She just never really seemed ... like with work, she never got irritated. She was pretty happy to be here."
