The Johnson County prosecutor handling the alleged DUI case against Natrona County Rep. Bill Allemand has filed rebuttals to defense motions to suppress evidence on constitutional grounds. The prosecutor argues the deputy's actions during the traffic stop, including placing Allemand in handcuffs, were justified due to concerns over the lawmaker's possession of a firearm and signs of potential intoxication.
Why it matters
This case highlights the complex legal issues surrounding DUI arrests, especially when they involve public officials. The prosecutor's response aims to counter the defense's claims that the deputy violated Allemand's constitutional rights, which could impact the admissibility of evidence and the outcome of the case.
The details
During the December traffic stop, the deputy observed signs of intoxication in Allemand, including unsteadiness and slurred speech, as well as a firearm in his truck. The prosecutor argues the deputy's decision to temporarily detain Allemand in handcuffs was justified for officer safety due to the presence of the firearm and potential impairment. The prosecutor also disputes the defense's claim that Allemand was handcuffed during field sobriety tests, stating body cam footage would support the state's assertion.
- On December 28, 2025, the deputy responded to a REDDI report and observed Allemand's truck nearly get into a crash before pulling into a travel center.
- The deputy approached Allemand's vehicle, noticed a pistol on the seat, and placed Allemand in handcuffs until another deputy arrived on the scene.
