A 24-year-old Tuscaloosa County man was charged with trafficking marijuana after narcotics agents discovered 6 pounds of weed and almost 500 bars of Xanax at a house in Coaling in August, according to court records filed Thursday.

The suspect, Shane Adam Herren, was arrested Wednesday after a monthslong investigation by the West Alabama Narcotics Task Force.

According to the deposition, a WANTF agent was given information in July that Herren was selling marijuana locally after having it shipped to him from California.

Agents searched a residence on Keenes Mill Road in Coaling in late August, where the homeowner had just received two mailed packages that were not addressed to her. According to the deposition, one contained more than six pounds of marijuana and 17 grams of cocaine. A second package held 492 bar tablets of Xanax-Alprazolam, a prescription tranquilizer intended to treat anxiety and other nervous disorders.

After more than a month of additional investigation, WANTF was able to link the drugs to Herren.

The 24-year-old was arrested Wednesday and charged with trafficking marijuana. He was placed in the Tuscaloosa County Jail, where he remained Friday morning pending a $500,000 bond.
