Two men were sentenced this week in U.S. District Court, Davenport, to federal prison in connection with a crystal ice methamphetamine investigation in Davenport.

Derrick Christopher Johnson, 50, of California, was sentenced Monday to 25 years on a single charge of conspiracy to distribute methamphetamine. Judge Rebecca Goodgame Ebinger also ordered that he will serve seven years of supervised released once he completes his sentence.

His co-defendant, Gary Eric Arnold, 50, was sentenced Tuesday to more than 11 years on a charge of conspiracy to distribute methamphetamine and 10 years on a charge of possession of a firearm by a felon.

Ebinger ruled that the sentences will run concurrent, or at the same time. Arnold must serve five years of supervised release once he completes his prison term.

There is no parole in the federal system.

According to a federal complaint filed in Johnson’s case and a plea agreement filed in Arnold’s case:

On Jan. 22, 2016, Arnold sold about 1.3 grams of crystal methamphetamine for $100 to a confidential source. The sale took place at Arnold’s home on West 69th Street in Davenport.

The same day, agents of the Quad-City Metropolitan Enforcement Group executed a search warrant at Arnold’s home and found approximately 75 grams of crystal methamphetamine, $15,590 in cash and a Remington Model 870 shotgun. Arnold is a convicted felon and is prohibited from possessing a firearm.

He admitted to police that he had been distributing approximately one pound of ice per month for the previous four or five months. He identified Johnson as his source.

Agents learned that the two men met about six months earlier and Johnson said he could provide Arnold with methamphetamine for $1,200 per ounce, which was a lower price than Arnold had been paying at that point.

Arnold told agents that he paid for the drugs delivered by Johnson at a rate of $14,000 per pound either by a bank or Western Union.

On May 5, agents located Johnson’s vehicle in the parking lot at the Iowa 80 Truckstop in Walcott and attempted to pull it over.

Johnson fled and struck two undercover police vehicles and two civilian vehicles. The vehicle eventually was stopped in the parking lot.

Agents who searched his vehicle found $4,272 in cash, 505 grams of ice, three cellphones and six credit/debit cards.

Johnson told police that he lives in Denver and frequently travels to California to care for his mother. He said he and his uncle, who was in the vehicle at the time of his arrest, had left California on May 2.

Johnson admitted that he met with his source and received four pounds of ice before leaving California. He admitted that he delivered three or four pounds of ice to a customer in Des Moines and then drove to Davenport to meet with Arnold and deliver the remaining pound to him.

Johnson said he was unable to meet up with Arnold and eventually gave up and started to drive home, according to the complaint.

The two men were indicted in federal court in late July.
