Client was charged with OWI in Tama County. After arresting the client and taking him to the Tama County Jail the officer requested a breath test from Client, only to discovery the breath testing machine produced error messages and was inoperable. Subsequently, the officer requested a urine sample. The officer collected the urine sample and sent it to the DCI lab for testing. The DCI lab refused to test the sample because the officer failed to transfer the sample to the proper sealed tube containing a preservative. The State amended the charge to public intoxication. The client never had his license revoked due to the improper urine collection.
