Thirteen men and two women participated in an Ashland prostitution ring that involved the exchange of hundreds of dollars in June, police said today.

Investigators sent the names of the alleged 13 johns and two prostitutes to the Jackson County District Attorney's Office Wednesday, said Detective Rick Spence with the Ashland Police Department.

Police cited one of the women, Annette Marie Wilson, 36, who they believe was the ringleader of the operation, for prostitution on June 30.

Spence declined to release the names of the other 14 people he said were involved in the prostitution ring, because they have not been charged with a crime. The district attorney's office may decide to file charges against some or all of the 14, he said.

"Ultimately it's up to the district attorney," Spence said. "I presented the case up to this point to them. They have the names of all of the men who had been identified and interviewed up to this point, so it's up to them if they decide to file charges and then the grand jury can decide to indict them."

Spence expects a Jackson County grand jury to hold an indictment hearing on the case during the week of Aug. 15. He will release more details on the case after the hearing, he said.

The 13 men allegedly met the two prostitutes, who advertised on the website Craigslist, throughout the month of June at Wilson's home, motels and private residences, all in Ashland, Spence said. The men paid between $90 and $200 per visit, depending on the services rendered, he said.

The men live throughout the Rogue Valley, he said. Wilson lives in Ashland and the other woman involved is homeless, but stays in Ashland and Talent, Spence said.

Detectives are continuing their investigation into the case and may identify more people who were involved in the prostitution ring.

Wilson was cited by Medford police for prostitution in two separate incidents in 2008 and 2009. In the 2009 case, which involved Craigslist postings, Wilson was charged with promoting prostitution, a felony.
