Deborah "Debbie" Flores-Narvaez Missing: Ex-Boyfriend Last to See Missing Vegas Dancer

LAS VEGAS (CBS/AP/KLAS) Police say a 31-year-old Las Vegas burlesque dancer Deborah "Debbie" Flores-Narvaez, who went missing more than a week ago, was last seen by her ex-boyfriend.

"It's hard," said Debbie's sister Celeste Flores-Narvaez. "I can't make anything of this right now. It's not her. It's not her to go missing. It's not her to take a small vacation like this, as some people might think, or she needed to get away. This was her life."

Las Vegas police say there is no evidence to suggest a crime has occurred. They say the dancer's ex-boyfriend has been cooperative.

Investigators are trying to retrace Debbie's steps before her disappearance. She was last seen December 12 at 7 p.m. leaving the Onyx Apartment-Condos in Las Vegas. The complex sits a few blocks away from the Luxor, where she performed in "Fantasy."

"It was a bad break-up," Celeste told CBS affiliate KLAS. "I'm hearing different stories that it was good, it was bad. There were times when she was upset about it."

Police say they have found Debbie's car. Her purse was found inside, and there were no signs of theft or violence.

Celeste, meanwhile, believes her sister is okay. She is making an emotional plea for Debbie's safe return. "She's just a very loving person," Celeste said. "Just let her go, and let her be, and let her come home to us and the people that she loves."
