(CHICAGO) A west suburban Aurora man was convicted Tuesday of charges stemming from his possession of as much as $1.3 million worth of marijuana, cocaine and meth.

In a jury trial, Gerardo Contreras-Gonzalez, 24, of the 500 block of North Lancaster Drive, was found guilty of two counts of possession of a controlled substance with intent to deliver, two counts of possession of a controlled substance, possession of marijuana with intent to deliver, possession of marijuana and unlawful possession of a firearm — all felony counts, according to the Kane County state’s attorney’s office.

In the morning Aug. 4, 2014, agents with Homeland Security Investigations and Aurora police searched Contreras-Gonzalez’s home and found 803 grams of crystal methamphetamine, 603 grams of cocaine, 9.145 grams of marijuana and a .45 caliber handgun, the attorney’s office said. Scales, a ledger and packaging materials were also found.

Authorities estimated the street value of the drugs to be between $550,000 and $1.3 million, prosecutors said.

Contreras-Gonzalez is scheduled to appear in court for sentencing Nov. 29. He faces between 12 and 50 years in prison.
