Why the Science Behind Your Case Matters

Most defense attorneys challenge DWI and criminal evidence through legal argument. Deandra Grant Law challenges it through the science. 

• Blood testing: Arlington DWI blood draws are analyzed by the Tarrant County Medical Examiner’s Forensic Laboratory (TCME) at 200 Feliks Gwozdz Pl, Fort Worth. GC-FID methodology, in vitro fermentation, sodium fluoride adequacy, chain of custody, analyst qualifications
• Breath testing: Intoxilyzer 9000. Partition ratio variability (1,100:1 to 3,400:1), 15-minute observation period compliance, calibration records, mouth alcohol, GERD/diabetes effects.
• Drug cases: Drug analysis routed to DPS Austin lab, Armstrong Forensic Laboratory, or NMS. Presence is not impairment. Pharmacokinetic analysis is how drug impairment evidence is properly challenged.
• Field sobriety tests: Deandra Grant is a trained SFST instructor who administers and grades the ACS-CHAL Forensic Lawyer-Scientist and DUIDLA Board Certification exams. SFST cross-examination goes to the protocol, not just the result.
• Digital evidence: Cell phone data, social media, CDR records, surveillance footage 
• Retrograde extrapolation: Rising BAC defense, Widmark formula, individual elimination rate variability
