Stacy Cheyenne Nunez-Barajas, a wealthy San Manuel tribal member sentenced earlier this month to electronic monitoring and five years probation for her role in a 2006 murder-for-hire plot, has been arrested for a violation of her sentencing agreement that could bring her 27 years in prison.

Nunez-Barajas, 26, was arrested just after 9 p.m. Friday at the San Manuel Indian Bingo and Casino in Highland, said San Bernardino County sheriff's spokeswoman Cindy Beavers.

Beavers said a deputy was called to the casino "in reference to trespassing."

It was not clear Saturday what the violation was. Available online court records for Nunez-Barajas' probation terms do not mention the casino as a prohibited place.

She was being held Saturday at the West Valley Detention Center in Rancho Cucamonga. Information from the jail's Web site showed she was in custody without bail.

On Nov. 6, Nunez-Barajas was sentenced to one year of electronic monitoring and her brother, Erik Barajas, 36, received six months for their roles in a highly publicized case linking them to the Mexican Mafia and the methamphetamine trade in the Inland Empire.

Nunez-Barajas faced 27 years in prison if she violated the terms of her sentencing agreement and Barajas faced eight years, according to court records.

The Barajas siblings, both convicted gang members, accepted plea agreements in the case that alleged they conspired to kill bar manager Leonard Epps on Sept. 30, 2006.

Epps, 37, was manager of the Brass Key bar in Highland and had a confrontation with Nunez-Barajas in March or April 2006, records say.

San Bernardino police, then investigating the drug activity in the area, learned of a plot against Epps and quietly spirited him into hiding several days before he was to be shot with a .40-caliber Glock handgun, court records say.

He has been hiding ever since.

On the day of their sentencing, Epps' attorney, Frank Peterson, served the Barajas siblings with a $50 million lawsuit.

Peterson read a victim-impact statement that complained that Epps had to live a life on the run while his would-be killers were sentenced to home monitoring.

"I think it's sad. . . . She is throwing away her entire life just because she wants power -- people to look at her and be afraid," Peterson said Saturday.

Nunez-Barajas' attorney, Albert Perez Jr., did not respond to an e-mail or a call to his answering service on Saturday seeking comment.

Jacob Coin, a spokesman for the San Manuel tribe, also declined comment.
