looked out of the window, he saw a white bag and a shotgun lying on the ground below. On closer investigation it was discovered that what appeared to be a white bag was actually a pillowcase containing a Smith and Wesson .40 handgun, a box of .40 ammunition, a box of 20-gauge shotgun shells, a hand-rolled marijuana cigarette, two bags of marijuana and one aluminum foil package containing one dose of heroin. The pillowcase and items found therein, and 20-gauge shotgun were immediately retrieved by Agent Castagnetta. Prior to taking defendant and Tobias downstairs, Detective Ballard was advised by defendant, who is handicapped, that he needed medical supplies out of his black backpack. Detective Ballard searched the bag to insure there was no weapon, and discovered one aluminumhim when he heard defendant on the phone making a drug deal. Thereafter, defendant asked Shief to "make a run," or deliver drugs to New Orleans. Shief further stated that it was not the first time he had helped defendant deliver drugs. Shief then explained prior deliveries he made in which defendant gave him the drugs and designated the spot for delivery.
Detective Bruce Harrison, an expert in the identification, use, packaging, distribution and value of controlled dangerous substances, testified that dealers commonly use couriers to make drug deliveries. He explained that a courier distances the dealer from the drugs.
The forty units of heroin found in Shief's vehicle were packaged in wax paper bags and matched packaging material, wax paper bags and black rubber bands, found in defendant's bedroom.
