A Franklin County man was sentenced Friday to serve more than 5 years in prison in a methamphetamine conspiracy case, the U.S. attorney’s office reported.

Ronald Dobsch, 51, Union, was sentenced to 70 months in federal prison by U.S. District Court Judge Jean C. Hamilton.

Dobsch pleaded guilty in March to one felony count of conspiracy to possess pseudoephedrine for the manufacture of methamphetamine, and possession of pseudoephedrine.

Sentenced previously in the case was Vicki York, 41, St. Clair, who was ordered to serve 100 months in prison on the same charges. She pleaded guilty in February and was sentenced May 18, the U.S. attorney’s office said.

The case was investigated by the Franklin County Narcotics Enforcement Unit.
