A Nevada man who police said received a package in the mail containing at least $30,000 in marijuana was arrested Wednesday.

Carl William Duncan, 29, was charged with possession of marijuana with intent to deliver and with violating drug-stamp laws after officers discovered that a Federal Express package addressed to Duncan had a 30-pound stash of processed marijuana inside, said John Tinker, director of the Central Iowa Drug Task Force.

Tinker said officers from the Anaheim, Calif., Police Department tipped off the Task Force earlier this week that a package identified by an Anaheim drug dog as having a large amount of marijuana would be arriving in Ames Wednesday.

The package was intercepted by the Story County Sheriff’s Office early Wednesday, and after the Story County drug dog, Bear, also indicated it contained marijuana, a search warrant was obtained to open the package, said Cpt. Gary Foster, public information officer for the Story County Sheriff’s Office.

Officers found what Tinker estimated was between $30,000 and $40,000 worth of marijuana, already processed into the compressed bricks that Tinker said drug dealers use to transport large amounts of marijuana. The package was then resealed and delivered to Duncan’s residence by an undercover Task Force officer, Tinker said.

After the delivery, officers obtained another warrant and searched Duncan’s Nevada home at about 10:30 a.m. Wednesday. Foster said the marijuana was then recovered from inside Duncan’s home, and he was placed under arrest.

Tinker said Duncan was not a known drug dealer in the area. “We were not aware of him prior to this situation,” he said.

Duncan is now being held at the Story County Jail awaiting an initial court appearance, which as of Wednesday had not yet been set, Foster said.

Duncan was charged with two class-D felonies, possession with the intent to deliver and violation of the drug-tax stamp, as well as one count of prohibited acts, an aggravated misdemeanor. If convicted, he would face a prison term of up to 12 years and fines of up to $20,000.

Tinker said officers also will be notifying Anaheim police of the arrest and will recommend them to take proper action against the package’s sender.
