State police say their K-9 unit found 10,000 oxycodone pills after troopers stopped a truck on I-95 in Milford.
Police say John Carlos Torres, 30, appeared agitated while talking on the phone at the service center Wednesday afternoon.
Police say they followed Torres, stopped his truck, and then called a police dog to the scene.
They say the dog found the pills, which are valued at more than $200,000.
Given the amount of drugs found, state police say they turned the case over to the U.S. attorney's office.
