Authorities in California seized 18 pounds of fentanyl last week, enough of the synthetic opioid to kill four million people and possessing a street value of around $1.25 million.

The bust, which happened on October 16, also netted numerous other drugs, a loaded handgun, and over $70,000 in cash.

Law enforcement arrested a man suspected of possessing the massive drug stash, setting his bail at $2 million.
