A pain doctor from Metairie who admitted committing health care fraud, threatening to kill law enforcement agents and plotting to illegally dole out pharmaceutical drugs received a 10-year prison sentence Wednesday from U.S. District Judge Martin Feldman.

Shannon Christopher Ceasar, 45, also was ordered to pay back more than $150,000 he bilked from Medicare, Medicaid and Blue Cross Blue Shield of Louisiana.

He surrendered his medical license as well as 33 guns authorities seized when they arrested him in July 2016.

Authorities had charged Ceasar with selling loads of prescriptions for money and sex while also falsifying patient files.

Agents noted during the case that they found a prescription in Ceasar's sports car that had been issued in the name of a man who later died of a drug overdose.

Ceasar at one point was recorded threatening to kill both narcotics agents and members of the state's medical licensing board as he grew worried his offices would be raided.

"What I'll do is make Baton Rouge look like a (expletive) kindergarten," Ceasar said days after a lone gunman fatally shot three law enforcement officers in the state's capital city. Ceasar also spoke of having an arsenal "large enough to supply a small militia" and promised to kill "every single one of those sons of bitches," officials charged.

He was facing up to 20 years in prison on his admission to drug conspiracy and 10 years each on the threats and health care fraud.

His office manager, Stephen Guilbault, pleaded guilty in November to plotting to use Ceasar's pre-signed prescription forms to prescribe the drugs oxycodone, hydrocodone and dextroamphetamine to himself, a girlfriend and a relative. Percocet, Vicodin and Adderall contain those medications.

Guilbault also pleaded guilty to conspiring to issue prescriptions to patients when Ceasar was out of the office, despite lacking a license to do that. The patients included Medicare and Medicaid beneficiaries who didn't need the prescriptions, costing those programs roughly $46,000, prosecutors said.

Guilbault's sentencing is set for May 2. He faces up to five years in prison and has agreed to pay restitution to Medicare and Medicaid.

Ceasar's office, Gulf South Physicians, was on Houma Boulevard. Guilbault co-owned it.
