Four Arrested, 20,000 Pills Seized After SF Teen's Fatal Overdose

The death of a 16-year-old San Francisco resident from a synthetic opioid more potent than fentanyl has triggered a major narcotics enforcement operation — and exposed a gap in California law that could let dealers walk. Mayor Daniel Lurie, SFPD Chief Derrick Lew, District Attorney Brooke Jenkins, and the Department of Public Health's behavioral health director announced four arrests, the seizure of over 20,000 counterfeit pills and three firearms, and an urgent call for Sacramento to act.

• Four suspects arrested after months-long undercover investigation into counterfeit pill network linked to teen's death

• Over 20,000 counterfeit pills and three firearms seized from three San Francisco residences

• DA Jenkins calls on state legislature to classify cycloprophine as a controlled substance, warning current law forces prosecutors to rely on untested legal theory

• Narcan works against cycloprophine but rapid response is critical; fentanyl test strips cannot reliably detect the new drug

• San Francisco recorded its fewest overdose deaths on record over the summer, but officials warn a deadlier opioid now threatens progress

In April, a 16-year-old San Francisco resident was found dead after ingesting counterfeit pills that tested positive for cycloprophine — a synthetic opioid that investigators say is more potent than fentanyl. The teen's mother cooperated with law enforcement, launching what became a months-long undercover operation by SFPD's narcotics unit.
