JOHNSTON COUNTY, N.C. — A traffic stop by Johnston County sheriff's deputies helped crack a federal drug investigation involving puppies.
Agents say Colombian drug dealers surgically implanted liquid heroin and cocaine into the dogs. Three of the puppies died from infections.
Colombian police adopted the surviving dogs. They are training one to sniff for drugs.
Thirty people are currently in custody. They are also accused of concealing the heroin in body creams and aerosol cans. The total street value of the bust is estimated at $7 million.
