  • DISMISSED DUI
    • 2024
    The Client was stopped for running a stop sign. The Client asserted that the odor of alcohol, glassy blood shot eyes, and the alleged failure to properly perform voluntary field sobriety maneuvers (SFSMs) did not create probable cause for the DUI arrest in this case. The client provided breath samples, which created an alleged breath alcohol concentration measurement of nine one-hundredths of one percent (0.090%). The Client argued the audio and video recording of the Client in the case did not support the probable cause for a DUI arrest, where the officer failed to substantially comply with the National Highway Traffic Safety Administration protocols for administering SFSMs to support probable cause. The court agreed and the Court suppressed evidence and the DUI charge was DISMISSED by the prosecution.

The Client was arrested for a DUI charge and asserted his statutory right to refuse to provide warrantless breath samples for chemical testing in a DUI case. After law enforcement applied for a warrant, the blood samples were analyzed and created an alleged blood alcohol concentration (BAC) measurement of twenty one-hundredths of one percent (0.20%). After filing numerous suppression motions on behalf of the Client and indicating the client was ready to go to jury trial, the prosecution agreed it could not prove a DUI charge, despite the alleged BAC measurement and the prosecution DISMISSED the DUI charge.

    • 2023

    Case: The Client did not deny that the Client failed to illuminate his headlights as he pulled out of a parking lot that was well illuminated. After the detention, client denied that odor of alcohol and bloodshot eyes allowed law enforcement to extend the detention in this case. The client explained to law enforcement that he had a recent knee surgery, which prevented law enforcement from administering standardized field sobriety maneuvers (SFSMs) to try to prove alcohol impairment. Unfortunately, the arresting officer relied upon SFSMs to arrest the client for a DUI charge. The Client was arrested for a DUI charge and allegedly provided breath samples resulting in a breath alcohol concentration (BrAC) measurement of eighteen one-hundredths of one percent (0.18%).

    Result: After filing numerous motions on behalf of the Client claiming the field sobriety maneuvers and chemical testing measurements were not valid, the prosecution agreed that it could not prove a DUI charge and the prosecution DISMISSED the DUI charge.

When the Client was contacted by law enforcement, the Client refused to answer any questions or to perform standardized field sobriety maneuvers (SFSMs) at the request of law enforcement. Because the Client smelled like alcohol, was blocking the entrance to a private roadway, and refused to cooperate with questioning by law enforcement, the Client was arrested for a driving under the influence of alcohol (DUI) charge. The Client asserted his statutory right to refuse to provide warrantless breath samples for chemical testing under Wyoming's implied consent law and the arresting officer obtained a telephonic warrant for blood samples. The Client's blood was drawn six (6) - six hours after the Client's DUI arrest and created an alleged blood alcohol concentration (BAC) measurement of one five-hundredths of one percent (0.05%). Over the Client's objection, the trial court allowed the prosecution to present retrograde extrapolation evidence to the jury to claim that the Client had an alleged BAC range of one one-hundredths of one percent (0.11%) to twenty-two one-hundredths of one percent (0.22%).

The arresting officer further claimed that the Client appeared to be impaired while walking to his vehicle and appeared to have urinated himself. The Client was arrested for DUI and provided breath samples, which created an alleged breath alcohol concentration (BrAC) measurement of nine one-hundredths of one percent (0.09%). The Client suffered from a medical condition called ACID REFLUX, which the Client argued caused an inflated BrAC measurement in this case. The Client claimed there was no probable cause for the DUI arrest and the BrAC measurements were not valid in this case.

    Result: After a motion hearing in the case, the trial court agreed that there was no lawful basis to detain the Client and the trial court suppressed all the evidence resulting in the dismissal of the DUI charge.

When law enforcement contacted client, they claimed to smell the odor of marijuana and relied upon field sobriety maneuvers to arrest client for driving under the influence of marijuana/drug (DUID).
