Police dog sniffs out millions in drugs A NYPD police officer and police dog stand guard at the entrance at the U.S. Open Tennis Championships in a 2011 file photo. BENSALEM TOWNSHIP, Pa., July 17 (UPI) -- A police officer and his K-9 dog on routine patrol in the Philadelphia area stopped a truck containing $11.7 million in illegal drugs, police said. Officer Brian Cowden of the Bensalem Township, Pa., police force, pulled over a tractor-trailer with California license plates Sunday, and his dog Edo sniffed out the narcotics, 33 pounds of heroin and 20 pounds of "very pure crystal methamphetamine" destined "for the Delaware Valley," Township Public Safety Director Fred Harran said at a news conference Monday. Cowden, a 10-year veteran of the force, saw the driver and passenger of the truck "walking around suspiciously," and noticed several vehicle violations, Harran said. The dog, a Belgian Malinois trained to detect narcotics, then sniffed out the drugs. The driver, Estaban Valasco, and the passenger, Juan Ledesma-Nolasco, both of California, were arrested and arraigned before District Judge Joanne Klein, and were being held on $1 million bail, The Philadelphia Inquirer reported Tuesday.
