Jason "Blu" Griffith -- the one-time boyfriend of murdered Vegas showgirl Debbie Flores-Narvaez -- made a brief appearance in a Las Vegas courtroom Wednesday morning for his arraignment.

During the hearing, the charges were read aloud to Griffith; he said he understood the charges, and an automatic plea of 'not guilty' was entered on his behalf. The judge then set a preliminary hearing date of February 15. At that time, a judge will decide if there is enough evidence to order him to stand trial.

Until his next court appearance, Griffith remains held without bail at the Clark County Detention Center.

As Breaking Celebrity News previously reported, Flores-Narvaez, 31, was reported missing December 14 after missing rehearsal for her production, the Luxor's Fantasy show. Her dismembered remains were found in a downtown Las Vegas home last Friday, placed in cement-filled tubs. An autopsy showed she had been choked to death.
