HUNTSVILLE, Alabama -- The Madison-Morgan County Strategic Counterdrug Team (STAC) seized 87 pounds of marijuana that was being sent through the mail last week.

According to Sgt. Jerry King, deputy commander of STAC, the high-grade marijuana has an estimated street value of $776,000.

He said a majority of the marijuana seized was coming from California to be sold throughout Madison County.

King said STAC worked with the U.S. Postal Service and the ABC Board in a weeklong initiative to disrupt and dismantle the transfer of drugs using the mail.

Eleven suspects were arrested in Madison County in connection with the transport, and more are expected to be charged, possibly in California. He said the suspects were receiving packages containing anywhere between one and 15 pounds of marijuana. They were charged with drug trafficking and possession of a controlled substance in most instances, he said.

Cash was also seized during the initiative, he said.

"It's just huge," King said. "It affects our community."

King said STAC works with law enforcement agencies across the country, but could not confirm whether STAC is working with agencies in California in these cases.

Along with 87 pounds of marijuana, agents seized a variety of firearms from the people receiving the illegal packages.

The guns included two shotguns, an AK assault rifle, a sniper rifle, a revolver, a glock, and others, according to police.

King said the larger guns like the AK are unfortunately not uncommon to come across, but are the kind they are glad to get off the streets.

"These larger ones can be pretty dangerous," he said, adding that one of the guns is the kind used by snipers. "None of these guns are the kind you'd use for hunting."

King said several suspects had multiple guns, something he said makes marijuana more dangerous than people might think. King said dealers and buyers often engage in violence over money exchanged, which makes the drug itself dangerous to the community.

"It's a very long and enduring process," Capt. Mike Izzo said. "I credit Sgt. King and his guys. Just getting these guns off the streets makes it safer."

King said marijuana is transported across state lines in many ways, including tractor trailers and cars, some that are even altered to hold more drugs in hidden panels and in the dash.

A majority of the high-grade marijuana agents are seeing in Madison County is coming from states where the drug is legal, King said.

The suspects arrested in the investigation so far range in age from about 25 to 35 years old, King said.
