It’s a purer and dangerously more addictive form of meth than any form of the narcotic that police have seen manufactured in the Quad-City area.

And police say “ice meth” found its way into the hands of a Davenport woman and her daughter, who were arrested this week on federal drug charges.

Patricia Parris, 52, and her daughter, Angela Ryan, 35, have detention hearings scheduled for Friday in U.S. District Court, Davenport. Each is charged with conspiracy to distribute methamphetamine.

The Quad-City Metropolitan Enforcement Group conducted the investigation and made the arrests Monday, the agency’s director, Kevin Winslow, said Wednesday.

“It was imported through other sources and made its way to Patricia,” he said.

The two were distributing a form of the drug called ice meth that is imported from outside Iowa and commonly associated with Mexican cartels, Winslow said.

He said ice meth has a higher purity level that makes it more addictive and also raises its street value. It also is sold in larger batches, he said.

The form takes its street name from its appearance. Winslow said ice meth looks like shards of glass.

“It’s not anhydrous, and it’s not the one-pot method,” he said. “It’s not the shake-and-bake labs we commonly see around here.”

Parris and Ryan are accused of distributing the drug to multiple clients throughout the area, Winslow said.

The conspiracy lasted from November 2008 to November 2011. He said police conducted a search at Parris’ rural Davenport home earlier this year.

The investigation continues and more arrests are expected, he said.

“This isn’t Pablo Escobar,” Winslow said, referring to the Colombian drug lord. “But it’s still a cog in the wheel in the war on drugs.”

Ice meth has appeared in the Quad-Cities before, and smugglers will bring it here hidden in semitrailers or buses, Winslow said.

The Parris-Ryan case is the second methamphetamine conspiracy case involving multiple individuals investigated by the agency this year, Winslow said.

The other case involves Fernando Avila, Neil Bazan, Miguel Carreon, Lucero Gonzalez, Tiffney Hampton and Kristin Young, who are awaiting trial in U.S. District Court, Rock Island, on charges of conspiracy to distribute methamphetamine.
