Authorities said Zarco-Picazo sold distribution levels of cocaine to Jorge Valdez, who then sold it to customers. Those 14 kilograms of cocaine were found on Jan. 30 in Zarco-Picazo’s Nissan Z sedan, which was parked outside a home in the 2300 block of North Menard Avenue, prosecutors said. The cocaine was packed into several bricks hidden behind a speaker console, prosecutors said.

The heroin was found in a high-rise in the 4200 block of North Marine Drive, prosecutors said. Galeana-Gomez and Gonzaga are accused of conspiring to sell nearly two kilograms of heroin to an undercover law enforcement and someone who was surreptitiously cooperating, prosecutors said.

On the afternoon of Sept. 17, 2020, Gonzaga tried to sell the heroin to the undercover officer and informant in the buildings’ underground parking garage, prosecutors said. Gonzaga was arrested, and supplies to package the drugs were found in two 27th-floor units, prosecutors said.
