"One of Debbie's friends told a story of how feisty she was and almost immediately everybody laughed," Celeste tells us. "That was Debbie to a tee. She was definitely feisty, yet adorable at the same time. Everybody loved her."

"Debbie shared the stage with lots of celebrities, including Carrot Top who attended the memorial," Celeste adds. "It was incredible to see how many people my sister touched and how they all had wonderful memories of her. One of the most commonly used words to describe Debbie was 'passion.' She had such a passion for life, for her family and for her dancing career.

"Dancing was her life. She's always say 'when life throws you a curve ball, just shut up and dance'."

Debbie Flores-Narvaez, 31, was reported missing December 14 after not showing up for rehearsal for the Luxor's Fantasy show. Her dismembered remains were found in a downtown Las Vegas home last week, placed in cement-filled tubs. An autopsy showed she had been choked to death.

Debbie's ex-boyfriend, 32-year-old Jason "Blu" Griffith, was arrested in Las Vegas January 8 and charged with her murder.  He dated the showgirl for the better part of the past year, and had previously been charged with domestic battery in connection with an October 22 incident with Debbie.

It was simply too much for Celeste Flores-Narvaez to handle -- seeing up close the man accused of the gruesome murder of her beloved younger sister, Debbie.

In an exclusive interview with RadarOnline.com, Celeste told us what was going through her mind -- and through her heart -- when she shouted at Jason "Blu" Griffith during his arraignment in a Las Vegas courtroom Wednesday morning.

"When I walked into the courtroom and looked at Jason, I burst into tears. I couldn't hold back the pain I felt and yelled, 'I hope you rot in hell for what you did to my sister you bastard.'  An officer came over and gave me some tissue, it was too too much to handle", Celeste told us.

The sister of murdered Vegas showgirl Debbie Flores-Narvaez screamed at the suspect during his court appearance Wednesday morning, saying, "I hope you [expletive] rot in hell for what you did to her. I hope you rot in hell." Celeste Flores-Narvaez then left the courtroom in tears.

The outburst came as Jason "Blu" Griffith -- Debbie's one-time boyfriend -- made a brief appearance in a Las Vegas courtroom for his arraignment on charges related to her gruesome murder.

During the hearing, the charges (murder, domestic violence and destruction of evidence) were read aloud to Griffith, who was wearing a blue jumpsuit with his hands shackled. When Judge Chris Lee asked if he understood the charges, Griffith calmly responded "yes". An automatic plea of "not guilty" was then entered on his behalf.

Celeste Flores-Narvaez is lashing out over revelations that Jason "Blu" Griffith used Dexter, the hit Showtime series about a serial killer, as a means to lure her Las Vegas showgirl sister to her death, claiming that the 32-year-old is 'worse than this Dexter character.'

In an exclusive new interview with RadarOnline.com, Celeste slammed the suspected murderer, branding him 'demonic' and the 'worst of the worst.' Going on to claim: "He knew exactly what he was doing. He's going to get what's coming to him."

Celeste Flores-Narvaez is painfully grieving over the discovery of her sister's dismembered body.

In an exclusive interview with RadarOnline.com, she says she is "furious" that the police didn't share information about her sister's remains with her family, and wants accused killer Jason "Blu" Griffith to "suffer."

"I'll definitely be in court when Jason is scheduled to appear. There's no question about it," Celeste says. "I want to see this guy face-to-face. If there were no police officers in court, I'd handle him myself. He's a monster. He thought he could get away with this."

The sister of a missing Vegas showgirl has told RadarOnline.com she is starting to believe her sister met with foul play.
