Clara Strange was a 77-year-old white woman from Lufkin, Texas, who died on April 1, 2008, after going into cardiac arrest during a dialysis session at the DaVita Healthcare Dialysis Clinic in Lufkin. Her death occurred amid a cluster of sudden, unexplained medical emergencies at the clinic that month; several patients suffered cardiac arrests or severe complications during treatment.

Family members and witnesses reported unusual odors and symptoms during the incidents, including a strong bleach-like smell. Investigators later focused on a licensed vocational nurse employed at the clinic, Kimberly Clark Saenz, who was suspected of injecting bleach into patients’ dialysis lines. Saenz was arrested and charged in connection with multiple deaths and assaults; a jury later found her guilty of capital murder for five deaths and guilty on aggravated assault counts.

Clara Strange’s death, initially treated as a medical event, became part of the broader case that exposed these suspicious deaths at the clinic.
