Denver, CO criminal defense attorney Michael Sheehan shares his experience in handling CO DUI cases. He states that he has been handling DUI cases since 2003 and has worked on thousands of them, covering every scenario imaginable. Some cases involve blood test results, others involve breath test results, and some involve a refusal to submit to either test. In cases involving a refusal, he focuses on whether there is a justified reason for declining the test, which of course depends on the specific facts and circumstances of the case.

For cases involving blood or breath tests, he ensures that the tests were conducted properly, that the equipment used was correctly calibrated and functioning at the time, and that the officer administering the test followed proper protocol without taking shortcuts. Nowadays, nearly every DUI investigation is captured on a police-worn body camera, making it essential for him to review the footage closely. This allows him to critically assess the officer’s actions and confirm that the investigation was conducted thoroughly and according to procedure.
