BILLINGS – A Billings man with a prior conviction dealing methamphetamine admitted Tuesday that he intended to sell about 33 grams of pure meth.

Sean Gilmore, 47, pleaded guilty in U.S. District Court in Billings to possession with intent to distribute methamphetamine and possession of a firearm in furtherance of a drug trafficking crime.

Gilmore was sentenced in 2003 to over 12 years in prison for possession with intent to distribute methamphetamine.

In April 2016, not long after his release from prison, Gilmore possessed methamphetamine that he intended to sell in Billings.

Federal agents conducted four controlled purchases of the drug from Gilmore in January 2017.

A confidential informant made four separate purchases from Gilmore.

The FBI raided Gilmore’s shop in February 2017 and found over 3.6 grams of pure meth, meth paraphernalia and two firearms.

After the search warrant was executed at Gilmore’s shop, a witness came forward and connected Gilmore to Raymond Tetzlaff and Crystal-Busby Tetzlaff.

The Teztlaff couple was charged with possession of methamphetamine after authorities found 2 pounds of meth, several firearms, plastic baggies and scales at their home.

Sentencing for the Tetzlaffs is set for Friday.
