Officers say they noticed indicators of suspected criminal activity, prompting them to call for a K9 to come help investigate. K9 Hector responded and quickly alerted his handler to the presence of drugs.

The car was then searched and about 80 pounds of drugs – including methamphetamine and around 100,000 blue “M30” pills suspected to have fentanyl – were discovered, CHP says. About $4,100 in cash was also found.
