Vickie Dawn Carson was born on February 13, 1966, in Montague County, Texas. Very little is known about her early life. She grew up in Texas, but details about her family and childhood remain scarce.

Vickie started her career in healthcare as a licensed vocational nurse in 1989. Throughout her career, she worked at several hospitals and a nursing home in North Texas. Her work mainly focused on caring for elderly patients. This experience provided her with skills critical for a nursing career. In late 2000, she got a job at Nocona General Hospital, a facility known for treating elderly patients with minor health issues.

Nocona General Hospital was recognized for its quality of care and was considered one of the nation's top 100 hospitals. Despite its reputation, the hospital was small and modest. Vickie's role as a nurse led her to work closely with patients who often had underlying health concerns.

During her time at the hospital, Vickie's life as a nurse was marked by routine responsibilities and direct patient interactions. However, there is not much public information about her personal life or her experiences while working in healthcare.

Between December 2000 and February 2001, Nocona General Hospital in Texas saw a sudden rise in patient deaths. All the deceased patients were between the ages of 62 and 100. Most of them had been in good health before their time in the hospital. At first, these deaths were attributed to advanced age and weakened immune systems. However, rumors began to circulate that someone might be intentionally causing these deaths.

Hospital administrator Charles E. Norris became concerned and contacted a pharmacist about a pattern he noticed. During this period, vials of Mivacron, a muscle paralytic drug, were reported missing. Initially, this was attributed to inventory issues since Mivacron was not considered dangerous at the time. After further investigation, Norris locked up the cabinets containing Mivacron and alerted the authorities.

A joint investigation between local police, the Texas Rangers, and the FBI followed. They looked into the deaths of more than 20 patients who might have been poisoned with Mivacron. Reports emerged about lawsuits against Vickie Dawn Jackson, a nurse who had been fired from the hospital. One lawsuit claimed she injected a polio patient named Donnelly Reid with a drug in his IV, but he survived thanks to another nurse's intervention. Sadly, he passed away two months later from pneumonia. Another lawsuit was filed by the family of 87-year-old Boyd Bruce Burnett, alleging that Jackson injected him with an unprescribed drug, which led to his death on December 24, 2000.

Jackson was arrested on July 16, 2002, while working at a local grocery store. She faced charges for four capital murders. At this time, authorities were still exhuming bodies to check for other potential victims. Her bond was set at $2 million, but it increased to $6 million after she was charged with six additional murders in January 2004.

Jackson’s first trial ended in a mistrial due to biased comments made by a prosecutor. A new trial was then moved to San Angelo. During the second trial, an FBI agent testified that Jackson killed patients out of anger for being "too demanding." When asked why she killed, she responded that she did not know. Ultimately, Jackson pleaded no contest to ten capital murder charges and accepted a life sentence in exchange for avoiding a jury trial.

She released a statement claiming her innocence and expressing sympathy for the families of her victims. However, her statement was met with little support. In 2015, Jackson and her legal team sought a new trial, but no new developments were reported. As of August 2021, she remains in prison, with the earliest possible parole date set for 2042.
