The 30-year-old was shot to death by husband rapper Eric Hayes on Monday in LosAngeles. Hayes then shot himself in what police are calling a murder-suicide.
"She was just an all around good person, a kind person," said Vancouver-based producer, director and choreographer Paul Becker.
Becker worked closely with Moseley for almost a decade on the TV series Hellcats, on movies such as Twilight, Mirror Mirror and Girl vs. Monster, and on numerous commercials.
"She was a phenomenal dancer," Becker said, adding the first audition video he ever saw of her's blew him away.
"She was one of the best dancers and one of the busiest working dancers in Los Angeles and Canada. She could do hip hop, jazz, she could do anything."
News of Moseley's death is affecting dance communities across Canada and the U.S., Becker said, because she had such an accomplished career and worked with so many people.
Becker, who is directing and choreographing in Florida now, said at least 30 dancers he's currently working with knew Moseley.
"She was fun. She was kind to everyone and nice to work with," Becker said.
The 30-year-old Vancouverite had moved to Los Angeles with big dreams for herself, but was always grateful to find work that brought her back home to be with her mother.
Moseley was raised by a single mother who sacrificed a lot to support her daughter's career, says Becker.
"[Stephanie] messaged me maybe three weeks ago thanking me for getting her jobs in Vancouver so she could be with her mom," he says. "Family was really important to her and she was so happy when she was with her mom."
"To have her mom be alone without Stephanie is so sad. Stephanie was her life."
Moseley's friends have set up a memorial fund to help her mother pay for funeral costs.
In all the years he worked with Moseley, Becker says he never saw any signs that she was in an abusive relationship. He did not know Hayes and didn't know much about him.
The last time Becker saw Moseley was three months ago, when he bumped into her at a Starbucks in LosAngeles. He says she seemed happy.
"It seemed like she was just living her dreams."
