The waitress accused by Huntington Beach police of selling cocaine at a downtown restaurant and bar pleaded guilty Monday to aiding in the selling of drugs.

Brynn Ashley Boucher, 24, was sentenced to three years of formal probation and a day in jail, the latter of which she has credit for, and ordered to pay fines and $2,000 to the Victim Witness Emergency Fund.

Initially, police said Boucher while on the job at the Killarney Pub & Grill sold cocaine to undercover officers on three different occasions in March, April and May. Those felony charges were dismissed.

Boucher is still employed by Killarney, according to her attorney, Ron Chrislip. She did not deal drugs, Orange County district attorney spokeswoman Farrah Emami said.

"She was not responsible for actually selling drugs to undercover officers," Emami said. "She was working in a bar and she put the officers in contact with the other defendant, the male defendant. She was an accessory in that she put the officers in contact, but she herself did not sell drugs."

Lt. Russell Reinhart said Boucher was just as responsible because she assisted in the sale of drugs.

The other defendant, Victor Mac Davis, 29, who police said assisted her in selling the drugs, pleaded guilty to selling and transporting drugs on four occasions. He was sentenced to three years of formal probation, 60 days in jail and ordered to pay fines and $2,000 to the emergency fund.

He is expected to volunteer with Caltrans instead of serving jail time.

Davis was convicted of selling drugs once before in Alameda County. Violating his probation could land him a maximum of 11 years in jail.

Boucher could also face jail time — up to three years — if she violates her probation.

Chrislip said police used Boucher to direct them to Davis, whom she knew as a bar patron, after giving her several drinks. Reinhart said Huntington Beach officers did not give Boucher any drinks.

It could have been the state's Department of Alcoholic Beverage Control (ABC) investigators who assisted local police in the bust, he said. But even if Boucher were given drinks, she chose to take them and wasn't forced to drink, Reinhart said.

Boucher also pleaded guilty to driving under the influence of alcohol and was sentenced to an additional three years of probation, a day in jail — which she also has credit for — and about $2,000 in fines.

Police arrested Boucher and Davis in May following a six-month investigation in response to alcohol-related problems linked to certain businesses downtown, including Killarney.

The information about the cocaine sales became known during the investigation.

ABC spokesman John Carr said the department is investigating Killarney, but he could not provide additional details. He said the investigation should conclude soon.
