A Billings special-education teacher was arraigned Thursday on felony drug charges.
Koby Gayle Murray, 48, appeared before District Judge Susan Watters and pleaded not guilty to four counts of fraudulently obtaining dangerous drugs. Watters allowed Murray to remain free without bond while her case is pending.
School District 2 officials announced earlier this week that Murray, a teacher at Lewis and Clark Middle School, had been placed on paid administrative leave as the result of a criminal investigation.
Superintendent Terry Bouck said the district would also conduct its own investigation.
Murray was previously charged in 2007 with four felony counts of fraudulently obtaining dangerous drugs in a case that ended in a deferred prosecution agreement.
As part of the agreement, approved in August 2008, prosecutors said they would dismiss the charges in three years if Murray completed a number of tasks, including counseling and addiction treatment.
Murray was allowed to return to her teaching job in the fall of 2008.
The new charging documents filed this week allege in the first count that on April 14, Murray used a fake prescription to get Endocet at a pharmacy on Overland Avenue.
The second count alleges Murray received a valid prescription for oxycodone as a pre-surgery medication on May 30, then a week later received another prescription for liquid hydrocodone from a different doctor.
Murray failed to report the prior prescription, court records state. The doctor told investigators that she would not have approved the second prescription had she known of the prior oxycodone prescription.
The third count alleges that another doctor wrote Murray a prescription for Percocet on June 25 after Murray failed to report that she had received a prescription for oxycodone the previous week.
The last count alleges that in June, Murray again failed to report a previous prescription in order to get a prescription of oxycodone.
Murray reportedly gave a statement to investigators on July 12 and admitted to seeing 16 doctors. Murray said she told the doctors that she was not taking any other medications, court records state.
Investigators said Murray was given 36 prescriptions by 19 different doctors.
