MEDFORD, Ore. — Federal indictments were unsealed Monday against members of an alleged Southern Oregon heroin ring that was broken up last month.

The indictments unsealed in U.S. District Court in Medford allege 27-year-old Ismael Anaya of Medford ran the operation until last June, when he was stopped by state police and found with $13,000, then turned the job over to 33-year-old Eliot Delavirgen of White City.

Based on wiretaps, informants, and drug buys over a period of nearly two years, the indictments allege the two men bought heroin in Oregon, California and Mexico, then broke it down into smaller sizes and gave it to the others named in the indictment for sale primarily in the Rogue Valley.

Authorities say they will seek forfeiture of $840,000 in proceeds from the drug sales, including cars and weapons.

Six others were named in the indictment. They were identified as Medford residents Shannon Christopher Harrop, 20; Jerret Hooey, 21; Judith Potteiger, 28; Ronald Coutee, 54; Erica Lapizco, 31, and Anthony Albert, 46, of Gold Hill.

Jackson County District Attorney Mark Huddleston said the FBI and state and local investigators figure the arrests have stopped about half the heroin coming into the Rogue Valley.

The federal indictments on drug and conspiracy charges carry mandatory sentences of 10 years in prison, acting U.S. Attorney Kent S. Robinson said.

Anaya and Delavirgen remain in custody after their arrests last month, and are scheduled for trial Dec. 8. Five of the others indicted pleaded not guilty in U.S. District Court and were scheduled for trial Jan. 12. Potteiger was to appear for arraignment at a later date.
