A Cochise County doctor whose medical license was revoked a year ago pleaded guilty Monday to seeking someone to kill a former employee who cooperated with state and federal investigators looking into 3,500 opioid prescriptions written by the doctor during a 16-month period.

Glenn Gary Robertson entered a guilty plea to one felony count of conspiracy to commit murder involving the female employee who had once been his patient.  He also pleaded guilty to illegally administering a narcotic drug and operating a criminal syndicate related to his conduct in prescribing 415,665 opioid pills from February 2017 to June 2018.

Robertson’s pleas were part of a deal negotiated with the Arizona Attorney General’s Office that resulted the dismissal of several other felony charges. The deal stipulates Robertson will be sentenced to 12.5 years in prison -with the possibility of release after 10 years- and that he must serve 7 years of probation upon his release.

Robertson, 51, obtained his medical license in 2004 and practiced at his own clinics in Benson and Sierra Vista. He also worked for various medical facilities outside Cochise County.

In March, he was arrested at his Benson home after providing a man a rifle as down payment to kill the woman. The hitman was actually an undercover FBI agent. Since then, Robertson has remained jailed in lieu of $1 million secured bond.

Robertson was also indicted by a state grand jury in June on eight felony drug charges related to his involvement with Tim Evicci, another of the doctor’s patients. Court records show it was Evicci who informed authorities that Robertson wanted someone to kill the former employee and bury her body on his property.

At the time, Evicci was pending trial along with two dozen other people for transporting drugs for sale and other drug charges. He is scheduled for trial next year on multiple felony counts but told authorities he expects leniency for getting Robertson on record about the murder conspiracy.

Public records from the Arizona Medical Board show Robertson’s license was restricted in 2009 after he admitted writing a prescription for a non-patient. His clinical work was again restricted after Robertson suffered a stroke in 2015.

Then in December 2017, concerns brought forth by medical professionals in Cochise County led the medical board to place Robertson on probation. Two weeks after that sanction ended in June 2018, Robertson was notified the board was suspending his license on an emergency basis because the doctor ignored an order to undergo substance abuse testing.

The board formally revoked the license in November 2018.  But by then he was the subject of a drug investigation involving the U.S. Drug Enforcement Administration, Arizona Attorney General’s Office, Tucson Police Department, and Pima County Sheriff’s Department.
