A Grady County jury handed a 14 year sentence to Sharleen Nickle on Tuesday. Nickle was convicted of possession of precursor with intent to manufacture a controlled dangerous substance.
Grady County Assistant District Attorney Courtney Siess tried the case.
Nickle, who has one prior felony conviction - possession with intent to distribute - was arrested in February of 2012.
She and two other suspects were seen purchasing pseudoephedrine at the Walmart in Chickasha.
"They made efforts to appear they were not together and went to a Nissan separately," an affidavit from the Oklahoma State Bureau of Narcotics and Dangerous Drugs Control states.
The arresting officers learned one of the other suspects had been arrested for previously for manufacturing methamphetamine, according to the report.
"All had a pseudophedrine purchasing histories consistent with individuals sourcing pseudophedrine," the report reads.
The truck was stopped for a traffic violation. Upon being questioned about her purchase, Nickle said she planned to sell the box for $40 to a buyer in Lawton.
The report said, "Nickle knew that the individual in Lawton would use the boxes of pseudophedrine to manufacture methamphetamine."
Nickle said she assumed the other two suspects planned to sell their boxes for money or trade them for methamphetamine.
