One of the defendants from December's methamphetamine sweep pleaded not guilty Wednesday to possession and distribution of meth.
Another one of the 15 defendants had her case continued until later this month.
Sherry Nel--son, 40, of Oak Creek, appeared for a plea hearing in 14th Judicial District Court on Wednesday.
Nelson's lawyer, Kristopher Hammond of Steamboat Springs, said he was unable to reach a plea agreement with prosecutors.
Hammond and the District Attorney's Office had been working on a deal for the past few months.
Without an agreement, Hammond entered a not guilty plea for Nelson.
Nelson, who was released from Moffat County Jail on bond Jan. 9, said nothing during Wednesday's hearing.
Chief Judge Michael O'Hara set Nelson's case for trial Aug. 2.
O'Hara set a pre-trial conference in the case for June 27. The conference will be Nelson's last chance to enter a guilty plea and accept an agreement, O'Hara said.
Sherry Bristow, 21, of Craig, also appeared in Dis--trict Court on Wednesday for a plea hearing.
Bristow's lawyer, public defender Sheryl Uhlmann, said she was close to working out a deal with prosecutors.
Terms of the deal were not disclosed.
O'Hara continued Bristow's case until May 23.
Local law enforcement officers and the Greater Routt and Moffat Narcotics Enforcement Team arrested Nelson and Bristow and 13 other defendants in December after a six-month investigation.
All 15 people are charged with meth distribution and possession.
Police say they have evidence that all 15 people sold drugs to undercover officers and informants.
