Thornton resident Heather Knoll claimed she sold thousands of dollars worth of cocaine and methamphetamine to University of Colorado students near Folsom Field during football games.

Knoll, 42, a suspected member of a Northern Colorado drug syndicate, boasted to a confidential informant that about 60 CU students paid her $6,000 a game for her “Blue Ice/Blue Meth” and “Shiny White” cocaine.

During a Sept. 28 meeting with the informant, Knoll sold 117 oxycodone pills for $3,500, according to a 30-page forfeiture complaint filed Monday in U.S. District Court in Denver.

That meeting was just one sting in a series of drug buys orchestrated by Drug Enforcement Administration agents over the past nine months across Colorado.

Federal prosecutors cite the illegal deals in their forfeiture lawsuit in an attempt to confiscate homes owned by Knoll and Richard “RichyRich” Martinez, a reputed Commerce City drug kingpin. Martinez, 35, was arrested Mach 22 on federal probation violations and on felony drug charges in Adams County.

The court documents expose Martinez’s drug syndicate, which ships drugs and money between Colorado and Juarez, Mexico; El Paso, Texas; Chicago, Indianapolis and West Virginia.

Knoll, who was allegedly caught transporting $250,000 in hidden car compartments to different states, allegedly used drug proceeds to buy a home at 10131 Grape Court in Thornton for $240,000 in May of 2016, records show. The U.S. Attorney wants to seize the home.

Prosecutors also want to confiscate two homes Martinez owns. Martinez bought the Commerce City home known as “the castle” at 9849 Jasper St. for $326,000 in 2004. He allegedly used it as both a marijuana grow and narcotics stash house, court records show. In November, when he bought a home at 10021 E. 145th Ave. in Thornton for $737,000, he moved in but kept the castle and continued to use it for his drug business, prosecutors allege.

A confidential informant showed a DEA agent a video of Knoll counting out $20,000 on a machine on June 28. The informant said Knoll makes weekly trips as a drug and narcotics courier for Martinez, who is her cousin. The informant also alleges Knoll has multiple prescriptions for hydrocodone, oxycodone and diazepam and sells the pills on the black market.

A second confidential informant spoke with members of the DEA’s Strike Force Group, claiming that Martinez imports and exports large quantities of heroin, prescription pain killers, methamphetamine and cocaine from Mexico.

The informant said Martinez carries up to 10 phones and uses sophisticated hiding spots in his home including compartments beneath his hot tub and in the walls. Martinez’s fleet of high-end vehicles includes two Mercedes SUVs, a GMC Denali pickup truck, a Saab and a Dodge Stratus. The cars all have hidden compartments for drugs and cash, the informant said.

Martinez, who carries drugs in a cut-out pocket in his Bible, met his supplier, a man from Juarez man identified only as Tony, while both were serving time in a Colorado prison.

Martinez, who also owns R&J Trucking, allegedly paid “the fat mechanic,” $9,000 per trip to ferry drugs from El Paso to West Virginia, the informant told DEA agents.

On Oct. 19, the informant met Knoll at 11:55 a.m. in the parking lot of Sprouts Shopping Center at 555 W. S. Boulder Road in Lafayette. The informant gave her $700 for two ounces of methamphetamine, court records say. She told him her boss could get thousands of oxycodone pills for $30,000 in Mexico. She then offered to get more pills and give the informant a discount, court records say.

She also told the informant her doctor prescribes an anti-anxiety drug to help her cope with the stress of driving large amounts of drugs through customs and border protection checkpoints.

Stings involving Knolls, and sometimes Martinez, continued through early March.

On Nov. 11, Pueblo police pulled Knoll over and found 15 pounds of marijuana inside two suitcases and $118,955 in a hidden compartment of the Pontiac Bonneville she was driving. On Jan. 26, a Colorado State Patrol trooper found more than $40,000 hidden in a speaker system of an SUV Knoll was driving to Chicago, court records say.

On Thursday, DEA agents executed a search warrant at 9849 Jasper St. and at a Bennett home where they found 374 grams of marijuana, 23 cellular phones, a butane hash oil extractor and 17 guns including high-powered rifles, according to records.
