Authorities have dismantled a heroin ring operating in Jefferson County and metro Denver, seizing $264,400 worth of drugs and convincing a district grand jury to return a 61-count indictment against six men.

The Office of District Attorney Peter Weir considered the men’s operation to be highly organized. Members of the enterprise received shipments of heroin from outside Colorado and stored the drugs in stash houses, according to a statement.

Potential buyers called and spoke with a dispatcher who told them where and when the drugs would be delivered, according to the statement. A runner met the buyer and then gave the cash to Fermin Flores-Rosales, 41, who in turn wired some of the money to people outside the U.S.

Investigators seized or made undercover purchases of 3,305 grams of heroin.

“This indictment and the dismantling of this heroin ring goes a long way towards stopping the flow of heroin into our community,” Weir said in the statement.

In addition to Flores-Rosales, the other five men indicted were 47-year-old Cristobal Flores-Rosales, 24-year-old Juan Borques Meza, 30-year-old Mario Acosta-Ruiz, 21-year-old Yoel Soto-Campos and 25-year-old Joel Torrez-Espinoza. The men were accused of violating the Colorado Organized Crime Control Act from April to December.

The indictment was returned Dec. 22. Five of the men have been arrested and are due in court on Jan. 16. Authorities have issued a warrant for Torrez-Espinoza.
