Authorities suspected that Larry Randy Stephenson was trafficking in illegal drugs. He was the subject of an on-going investigation. He was arrested for delivery of four ounces of cocaine to a confidential informant on August 13, 1992. When asked about his source, Stephenson stated he bought the cocaine from Gillespie at 4028 Hubbell Avenue, apartment 267, in Des Moines. Stephenson believed Gillespie had more cocaine at his residence, 3008 East Washington. At this point Stephenson agreed to cooperate with the authorities. On the basis of the information Stephenson provided, an agent working on the case and an assistant Polk County attorney went to District Judge James Brown seeking an anticipatory search warrant for the Hubbell apartment and the East Washington residence. Judge Brown granted the warrant, conditioning probable cause to search upon the happening of three events. Briefly, these events were (1) Stephenson would make a controlled buy of cocaine from Gillespie, (2) Stephenson would bring the cocaine back to agents after the transaction, and (3) the substance Stephenson purchased would either field test positively for cocaine, or appear to be cocaine. All three events occurred. The warrant was executed at both addresses. Evidence of illegal activity seized from the Hubbell address was later suppressed. Evidence from the East Washington address was used by the State to convict Gillespie. Authorities suspected that Larry Randy Stephenson was trafficking in illegal drugs.
