San Francisco, CA –  Today, San Francisco District Attorney Brooke Jenkins announced that two individuals were charged in connection to narcotics trafficking in the Tenderloin.  Jeremy Gonzalez-Sierra (21) and Ronald Murillo-Zelaya (23) were arraigned on April 3, 2024.  They each pleaded not guilty to all charges.  Gonzalez-Sierra is charged with one count of possession for sale of cocaine base (H&S 11351.5) and Murillo-Zelaya is charged with five counts of possession for sale of controlled substances – fentanyl, Oxycodone, methamphetamine, cocaine salt, and Xanax.   

“I would like to thank the San Francisco Police Department and all our other partners in law enforcement who are working tirelessly to close open-air drug markets, said District Attorney Brooke Jenkins.  “My office will continue to do everything we can to hold drug dealers accountable while reinforcing our message that San Francisco remains steadfast in its commitment to public safety for all.”

According to court records, on March 31, 2024, San Francisco Police observed Mr. Gonzalez-Sierra and Mr. Murillo-Zelaya engaged in what appeared to be a narcotics transaction in the Tenderloin.  Further investigation resulted in the seizure of 700 grams (approximately 1.5 pounds) of fentanyl as well as other controlled substances from Mr. Murillo-Zelaya.

The next court date for both Mr. Gonzalez-Sierra and Mr. Murillo-Zelaya is April 16, 2024, in San Francisco Superior Court Department 11, for the preliminary hearing in this matter.  The District Attorney’s Office moved to detain both Mr. Gonzalez-Sierra and Mr. Murillo-Zelaya pending trial because of the public safety risk they pose.  The court granted the motions to detain without prejudice and set no bail for either of them.  The court will hear further arguments on the motion to detain at a future hearing.   

Although charges have been filed, this remains an active investigation.  Anyone with information is asked to call the San Francisco Police Department Tip Line at 1-415-575-4444 or Text a Tip to TIP411 and begin the text message with SFPD.  You may remain anonymous.
