A former Casper doctor has been arrested for illegally buying steroids, according to Natrona County Circuit Court records.

Paul Michael Harnetty, 46, was charged with unlawfully possessing Nandrolone, a Schedule III controlled substance, according to the criminal information document signed by Assistant District Attorney Brett Johnson.

If convicted, Harnetty faces up to five years of imprisonment and up to a $10,000 fine.

He was taken into custody in Hennepin County, Minn., on Jan. 20, and will return to Casper, according to the county's court records.

Last April, he attempted to obtain 12 10-milliliter bottles, or 3.6 grams, of the synthetic steroid Nandrolone, according to an affidavit filed with the court on Jan. 12 by an agent with the Department of Homeland Security, Immigration and Customs Enforcement.

Harnetty had contacted a proprietor of an online business named HK Market, based in Guangdon, China, and ordered the Nandrolone to be sent to his address, which was redacted in the affidavit. On April 18, the U.S. Postal service delivered a package coming from a man in Parker, Colo., to Harnetty at his address.

After that, law enforcement officials executed a search warrant at Harnetty's address, found the box that had contained the Nandrolone, computers, cell phones and other evidence.

Harnetty had worked as an obstetrics/gynecologist at the Wyoming Medical Center.

On Oct. 7, the Wyoming Board of Medicine accepted his voluntarily relinquishment of his license because of a continuing investigation against him for wrongful practice.
