On Friday, Bucio-Perez and Espinoza-Zepeda sold and delivered the laced black tar heroin to an undercover cop, prosecutors said. The officer was working on a joint investigation conducted by the Drug Enforcement Administration, the Kane County sheriff’s office and the Chicago and Elgin police departments.
The laced heroin has an estimated street value of $1 million, prosecutors said.
Both Bucio-Perez and Espinoza-Zepeda are being held at the Kane County jail on $7 million bail, prosecutors said. Bucio-Perez’s next court date was set for Feb. 21, while Espinoza-Zepeda is scheduled to appear in court the following day.
