Omo Ovella Glenn Wyler, a 95-year-old woman, passed away on January 24, 2001, in Nocona, Texas. She had been admitted to Nocona General Hospital for congestive heart failure but had been treated and was set to be discharged. However, she was administered an injection of mivacurium chloride a powerful muscle relaxant, which caused her to stop breathing.
Her death was later linked to a series of suspicious fatalities at the hospital, all occurring between December 2000 and February 2001. The deaths were investigated by local authorities, the Texas Rangers, and the FBI after hospital staff noticed a pattern and missing vials of Mivacron. The investigation led to the arrest of Vickie Dawn Jackson, a licensed vocational nurse at the hospital, who was accused of murdering at least ten patients using the drug. Jackson was convicted of capital murder and sentenced to life imprisonment.
The hospital faced lawsuits for negligence before Jackson was arrested. One lawsuit was filed by the children of Boyd Bruce Burnett, another victim, alleging that Jackson had injected him with an unprescribed drug that resulted in his death. Another lawsuit was filed by a polio patient who survived an injection but later died from pneumonia.
The case of Omo Ovella Glenn Wyler was part of a broader investigation into Jackson's actions, which revealed that she often targeted patients who had slighted her or had personal connections to her estranged husband. The tragic circumstances surrounding Wyler's death contributed to the eventual conviction of Jackson, ensuring justice for the victims and their families.
