LAS VEGAS - A missing burlesque dancer last seen by her ex-boyfriend told police he had beat her while she was pregnant with his child more than a month before her disappearance, according to Las Vegas police records.

Deborah Flores-Narvaez, 31, was reported missing Dec. 14 after she didn't show up for a rehearsal of "Fantasy," the nightly burlesque show at the Luxor hotel and casino where she worked.

She was last seen on Dec. 12 by Jason Omar Griffith, who has not been named as a suspect. Police said Griffith has been cooperative and there is no evidence to suggest Flores-Narvaez has been harmed.

But police records show the Las Vegas Strip dancer and her former beau had a rocky past.

Flores-Narvaez and Griffith had been dating for about a year when police responded to a domestic violence call involving the couple on Oct. 22.

Flores-Narvaez told police officers she had been visiting Griffith's ex-girlfriend when he showed up. She said he stole her iPhone and elbowed her in the chin, according to an arrest report.

He drove away, and Flores-Narvaez and the ex-girlfriend followed him.

Griffith stopped his car less than a mile away and confronted the women. Flores-Narvaez said Griffith threw her phone and told her that he was not going to jail, police said.

As she picked it up, she said he pushed her and then kicked her and pulled her hair while she was on the ground, according to the arrest report.

Griffith fled in his car.

She again followed him.

At a nearby intersection, he got out and kicked the side door of her vehicle, Flores-Narvaez told police.

Griffith told police the couple had been in an argument but denied hitting her or taking her phone.

He said he threw her phone after she taunted him with it.

He was arrested on battery, domestic violence and coercion charges.

Flores-Narvaez moved to Las Vegas to become a dancer. She previously lived in Maryland, where she served as an ambassador for the Washington Redskins in 2007, a non-performing position that sent her into the community.
