Judge sentences Jefferson County owner of of mushroom grow lab for possessing and intending to distribute methamphetamine

ST. LOUIS, MO – United States District Judge Stephen N. Limbaugh, Jr. sentenced Shawn Tepen to 90 months in prison today. The 32-year-old Cedar Hill, Missouri resident pleaded guilty to possession of methamphetamine with the intent to distribute.

Tepen was identified, in May 2019, as a suspect who was receiving a large number of suspected narcotics packages at his home on Golden Spring Court in Cedar Hill. Investigators, from the FBI and USPIS, worked with members of the Jefferson County Drug Task Force who advised they also received information Tepen was distributing meth and other narcotics.

On September 3, investigators learned Tepen would be receiving a package containing meth. On September 6, investigators located a package addressed to Tepen’s home with a return address from Los Angeles, California and a fake name listed as the sender. Investigators used a K-9 to sniff the package and the dog indicated a presence of narcotics. Investigators, using a search warrant, searched the package and discovered four pounds and 7.8 ounces of a crystalline substance later determined to be meth.

On September 9, an undercover postal investigator did a controlled delivery of the package to Tepen’s home. Eventually, Tepen left his home, picked up the package and went back into his home. Investigators, using an anticipatory search warrant, searched Tepen’s home and found a firearm with three magazines, 1,983.7 grams of meth and a large mushroom grow lab in the basement.

The FBI, U.S. Postal Inspection Service, and Jefferson County Drug Task Force investigated this case. Assistant United States Attorney Nauman Wadalawala is handling the case.
