Darke County deputies and the U.S. Postal Inspection Service uncovered a drug mailing scheme this week, which ended with a 33-year-old man arrested.
Cory Scarioni, 33, of Gettysburg, was arrested on suspicion of possession of marijuana.
Deputies said post office inspectors reported suspicious packages were being sent from California to a P.O. box in Gettysburg.
Detectives seized nearly 17 pounds of marijuana during the joint investigation, authorities said.
Scarioni also had a warrant for a parole violation out of California.
