The Iowa Court of Appeals reversed a district court decision upholding a search at the residence of Pamela Robbins.

Officer Bruce Rhoads of the Tama County Sheriff’s Department obtained a search warrant for Robbins residence and for the residence of Michael Watson. The search warrant was based upon Rhoads’ experience, Watson’s criminal history, Watson’s purchases of pseudoephedrine, Robbins’ purchases of pseudoephedrine, suspicious traffic near Watson’s house, and the presence of Robbins’ car parked at Watson’s house. Pseudoephedrine is a drug commonly found in cold medications and it can be used in the manufacture of methamphetamine.

During the search of the houses drug related items were found. Robbins and Watson were charged with various drug charges.

The Fourth Amendment mandates that a search warrant must be supported by probable cause. In other words there must be a nexus between criminal activity and the place to be searched. The nexus must be great enough that “under the totality of the circumstances a person of reasonable prudence would believe that evidence of a crime might be located on the premises to be searched.”

Nowhere was it alleged that Robbins purchased pseudoephedrine in amounts that exceeded the legal maximum or that she purchased it more often than permitted by law. The appellate court ordered the suppression of all evidence found at Robbins’ home due to the lack of probable cause. Probable cause, according to the court cannot be based purely upon the legal purchase of a precursor drug.
