From the AP article:

Police announced Wednesday they had arrested two men suspected in a plot to smuggle 417 pounds of marijuana, and seized a total of $3.6 million in pot. Investigators said the package that arrived on Calvo's porch had been sent from Los Angeles via FedEx, and they had been tracking it ever since it drew the attention of a drug-sniffing dog in Arizona.

Police intercepted it in Maryland, and an undercover detective posing as a deliveryman took it to the Calvo home.

Calvo's defenders — including the Berwyn Heights police chief, who said his department should have been alerted ahead of time — said police had no right to enter the home without knocking.
