A Kansas inmate, who police say has been at the center of manufacturing and distributing synthetic drugs in central Kansas, was charged Wednesday in federal court with selling a synthetic version of marijuana.

Eric Srack, 43, was charged in the U.S. District Court in Wichita with “selling a misbranded product known as ‘Aromatic Potpourri’ that contains a substance mimicking the active ingredient in marijuana,” U.S. Attorney Barry Grissom said in a news release Wednesday.

The criminal complaint alleges Srack sold such products between March 2010 and February 2011.

Srack was arrested in 2011 by Salina police following the death of Kansas University student Elijah Taylor, 21, who died after jumping into traffic on Interstate 135 near Salina.

Taylor had ingested synthetic drugs that he purchased from The Grind, a shop run by Srack that sold such products. Srack was convicted on three counts of illegal drug distribution, but he’s eligible for parole next year.

If convicted on the federal charges, Srack could face up to three years in prison.
