COLLIER COUNTY, Fla. - "It was just a bad scene," said Gina Eckelman.

Gina Eckelman said she knew there was something suspicious going on at her neighbors home.

"We had no idea what he was doing, I guess just judging by some of the characters."

Those characters - Kassem Bannout, Gregory Murphy, and Norma Gable - were arrested by Naples Police after a three month investigation involving the synthetic drug known as "spice."

Investigators focused on two locations, Bannout's business, the Everglades Convenience Store on 10th Street North. And the home he rented on Pine Court.

WINK News is learning last October, Murphy was a clerk at the store, when police say he was robbed at gun point. That suspect got away with $600. During this investigation, Postal Investigators intercepted a package, filled with drugs, that was supposed to be delivered to Bannout's home. Agents seized 470 packages of spice, leaving neighbors thrilled about the arrests.

"We have families here, we're all owners, he's a renter, you know he has riff raff coming into that house all the time."

The Postal Inspection Service said their detectives aggresively hunt down illegal shipments in the mail before making any arrests. And their investigative methods are sensitive and confidential.
