Ex-doctor enters plea deal in attempted murder, drug deals
TUCSON, Ariz. (AP) — A former doctor has reached a plea agreement after illegally dealing OxyContin and plotting to kill a woman he suspected of reporting him to the state medical board.
The Arizona attorney general’s office announced the Dec. 16 plea agreement on Monday.
Glenn Gary Robertson, 50, pleaded guilty to attempted first-degree murder, illegally conducting an enterprise and illegal administration of a narcotic drug, authorities said.
Robertson practiced in southeast Arizona before his medical license was suspended in June 2018, authorities said. His license was revoked in December 2018 after he prescribed Ritalin to a woman he did not examine, authorities said.
Robertson began plotting to have the woman killed after believing she reported him to the state Medical Board, according to court documents. He made a deal with an undercover officer to kill the woman in exchange for a rifle, authorities said.
“As payment for the murder, Robertson provided the ‘hitman’ with a scoped rifle which was valued somewhere between $500-$1,200,” the court documents said.
Drug Enforcement Administration officials were already investigating Robertson when they discovered the murder-for-hire plot, officials said.
The original investigation revealed Robertson used his medical license to illegally sell OxyContin between February 2017 and November 2018 and distribute the drug with a suspected drug dealer while still practicing medicine, department officials said.
The FBI’s Sierra Vista office and the Arizona attorney general’s office subsequently launched a joint undercover investigation, authorities said.
With the plea deal, Robertson will serve more than 12 years in prison for attempted first-degree murder, authorities said, He also faces more than 8 years on the charge of illegally conducting an enterprise and 7 years’ probation for illegal administration of drugs, authorities said.
A sentencing hearing is scheduled Jan. 27.
