Special District Judge Kathryn Nichols ruled Monday from the bench in Courtroom 304, granting a defense motion to suppress critical evidence and subsequently dismissing the state’s felony information with prejudice against 34-year-old Derrick Vance. Vance had faced up to five years in the custody of the Oklahoma Department of Corrections under [Title 47, Section 11-902](https://www.oscn.net/applications/oscn/Index.asp?ftdb=STOKST47) of the Oklahoma Statutes. The prosecution arose from an aggressive filing practice by the Oklahoma County District Attorney’s Office, which invoked amended provisions under 47 O.S. § 11-902(C) allowing prosecutors to aggregate two distinct DUI arrests occurring within a single 12-month period into a standalone felony charge—even before either underlying traffic stop had been adjudicated on its merits. The dismissal came after Vance’s privately retained [defense counsel](https://floridacriminaldefense.us/best-practices-for-choosing-a-criminal-defense-attorney/) demonstrated during a preliminary evidentiary hearing that the arresting officer lacked reasonable suspicion to stop Vance’s vehicle during the second incident, and that blood samples seized under a subsequent search warrant were handled in direct violation of state administrative regulations. ## The Statutory Architecture of Aggregated Charges Historically under Oklahoma law, a driver charged with operating a motor vehicle while impaired faced a misdemeanor under 47 O.S. § 11-902(A), provided the individual had no prior DUI convictions within the preceding ten years. Elevating a DUI to a felony typically required the entry of a formal guilty plea, a deferred judgment, or a prior conviction. Under revisions to Oklahoma’s statutory traffic framework, state lawmakers created a mechanism intended to target repeat offenders: if a driver accumulates two pending misdemeanor arrests within a calendar year, prosecutors may dismiss the lower-level Municipal or District Court dockets and re-file the matter directly in District Court as a consolidated felony. Prosecutors have argued the statutory pathway provides a vital tool to protect the public from dangerous motorists before formal trial dockets conclude. Criminal defense attorneys, however, have countered that the statute encourages law enforcement to stack dubious, marginal traffic stops to force plea negotiations under the threat of a penitentiary sentence. “The statute essentially allows the state to bypass the presumption of innocence,” said Vance’s private defense attorney, Raymond C. Thornton of the Oklahoma City criminal defense firm Thornton & Associates. “By cobbling two unrelated misdemeanor allegations into one felony bill of information, the District Attorney attempts to manufacture legal leverage where none exists under the facts. When you subject those arrests to strict judicial scrutiny, the entire case collapses.” ## The Two Stops: Northwest Expressway and Broadway Extension Court records indicate Vance’s legal exposure originated across two separate encounters with Oklahoma City law enforcement over a five-month span. The first incident took place on the evening of April 14, 2026, when an Oklahoma City Police Department patrol cruiser stopped Vance along the Northwest Expressway near Council Road, citing an allegedly unilluminated tag lamp. Vance performed standard field sobriety tests along an uneven, gravel-strewn roadside shoulder before officers placed him into custody for misdemeanor operating under the influence. That docket remained pending on the Oklahoma County misdemeanor docket with a disposition hearing scheduled for late autumn. The pivotal second stop occurred shortly after midnight on September 8, 2026. Officer Brent Larson of the Oklahoma City Police Department initiated an emergency stop on Vance’s 2022 Ford F-150 near the Broadway Extension and Northwest 63rd Street. In his sworn probable cause affidavit, Larson asserted that Vance’s vehicle was “weaving aggressively across marked traffic lanes” in violation of 47 O.S. § 11-309, creating an immediate highway hazard. Larson further attested that upon approaching the driver’s window, he detected the odor of alcohol and observed bloodshot eyes. When Vance exercised his statutory right to decline a voluntary roadside Intoxilyzer 8000 breath sample, Larson secured a telephonic search warrant to extract a forced blood specimen at OU Health University of Oklahoma Medical Center. Rather than proceeding on the two arrests as separate misdemeanor offenses, Assistant District Attorney Christopher Wallace dismissed the April case and filed a unified felony information under 47 O.S. § 11-902(C), listing Vance as a felony defendant facing statutory imprisonment and the permanent loss of his driving privileges. ## Cruiser Telemetry Refutes Officer Testimony During Monday’s preliminary hearing, the defense mounted a direct challenge to the legality of the September traffic stop under the Fourth Amendment, moving to suppress all resulting evidence, including the seized blood vials. Under direct examination by ADA Wallace, Larson reiterated the statements in his probable cause affidavit, testifying that Vance’s pickup truck drifted repeatedly outside its lane of travel. On cross-examination, Thornton introduced high-definition dashcam telemetry footage and synchronized automated vehicle locator (AVL) records obtained via a defense discovery subpoena. The continuous video record, projected on courtroom display screens, showed Larson’s patrol vehicle trailing Vance for nearly two miles along the Broadway Extension. Over that span, Vance’s passenger-side tires touched the painted white fog line on two occasions, but never crossed onto the paved shoulder. The recording established that the roadway was free of other vehicles, and Vance maintained a consistent speed of 62 miles per hour in a posted 65-mile-per-hour zone. Thornton cross-referenced the video with established Oklahoma jurisprudence, citing the Oklahoma Court of Criminal Appeals’ governing precedent in *State v. Emery* and *State v. Paul*, which holds that momentary or incidental contact with a lane marker on a multi-lane highway does not establish reasonable suspicion or probable cause under 47 O.S. § 11-309 unless the driving behavior poses an actual danger to surrounding motorists. “Officer Larson, at any point in that three-minute recording, did my client cross the line into adjacent lanes or endanger another vehicle?” Thornton asked. “He touched the outside marker twice,” Larson responded. “Based on the time of night, that indicated impairment to me.” “The appellate courts have ruled that touching the line is not a crime,” Thornton replied. “Without a crime, there is no legal basis to seize a motorist.” ## Failure to Follow State Phlebotomy Regulations Thornton then challenged the physical integrity of the state’s forensic evidence. The defense introduced certified hospital records and a sworn deposition from the registered phlebotomist who conducted the blood draw under warrant at 2:15 a.m. on September 9. Under Oklahoma Administrative Code (OAC) Title 40, Chapter 10, promulgated by the Oklahoma Board of Tests for Alcohol and Drug Influence, state forensic blood collection kits mandate that drawn vials containing sodium fluoride preservative must be inverted gently eight to ten times immediately upon filling to ensure chemical stabilization and avoid micro-clotting. Hospital deposition records confirmed that Officer Larson took immediate physical possession of the unmixed vials from the phlebotomist’s tray without performing the required inversions, rendering the subsequent toxicological gas chromatography screening scientifically invalid under state laboratory administrative rules. Wallace argued to the court that minor technical deviations should affect only the weight given to the evidence by a jury, rather than its admissibility. He further contended that the officer acted in good-faith reliance on the search warrant. Judge Nichols rejected the state’s arguments. “The Fourth Amendment is not a technicality, and administrative testing protocols are not optional suggestions,” Judge Nichols stated in her bench findings. “The dashcam evidence directly contradicts the sworn narrative in the affidavit. The officer lacked reasonable suspicion to initiate the traffic stop on September 8 under Oklahoma law. Consequently, the search warrant and all evidence obtained from that unlawful seizure are tainted.” ## The Ruling and Aftermath With the September traffic stop suppressed, Thornton moved for the immediate dismissal of the overarching felony information, noting that the statutory requirements of 47 O.S. § 11-902(C) could no longer be met without a valid second arrest. Judge Nichols granted the defense motion, barring the state from utilizing the consolidated statute and dismissing the felony matter with prejudice. Following the hearing, Vance expressed relief outside the courthouse. “When they charged me with a felony, my job and my life were on the line,” Vance said. “If I had just accepted what the police wrote down on that arrest report, I would have had to plead to something that wasn’t true. My attorney scrutinized every second of that dashcam video and held them to the law.” Thornton noted that the ruling demonstrates the necessity of aggressive defense litigation when dealing with aggregated criminal statutes. “The District Attorney’s office believed that by combining two marginal cases, they could mask the investigative defects in both,” Thornton said. “This ruling proves that when defense counsel investigates the telemetry, tests the statutory boundaries, and enforces administrative testing regulations, the government cannot sustain an unconstitutional charge.” The Oklahoma County District Attorney’s Office has not stated whether it plans to seek an appeal of the suppression order. Vance faces no remaining active criminal charges in Oklahoma County. ### Case Wins [Fleeing And Eluding Gig Work](https://floridacriminaldefense.us/fleeing-and-eluding-acquittal-tampa/) **Disclaimer:** Content reflects possible scenarios for defendants and not necessarily guarantee.
