John Gardner and his attorneys had asked the Supreme Court of the United States to review the case, alleging that his trial lawyers were ineffective.  Specifically, they argued that Jon's trial lawyers failed to provide evidence that John suffered from "abandonment rage," which allegedly causes men to kill their female companions with excessive force when faced with recent or imminent abandonment.  The Supreme Court has denied the request.  One of John's attorneys has stated that no other appeals are planned.  If executed, John will be the first inmate executed in the nation in 2020.

John Steven Gardner is scheduled to be executed at 6 pm local time on Wednesday, January 15, 2020, inside the Walls Unit of the Huntsville State Penitentiary in Huntsville, Texas. Sixty-four-year-old John is convicted of the murder of his wife, 41-year-old Tammy Gardner on January 23, 2005. John has spent the last 13 years on death row in Texas.

John was born in Mississippi. He graduated from high school and worked as a painter prior to his arrest. John received an 8 year prison term in Mississippi for shooting his second wife, causing her to have a miscarriage and making her a paraplegic. Additionally, John threatened his third wife and eventually kidnapped her when she attempted to leave him. Police arrested John and returned him to prison.

John Gardner married his second wife, Tammy, in 1999. According to those who knew her, after the marriage, Tammy lost weight, became introverted and lost her sparkle. Tammy had perviously been known as very outgoing and happy. Gardner allegedly threatened and abused her. Shortly after marrying, Tammy sent her daughter to live with her father for her daughter’s safety. Tammy had repeatedly told her friends and her boss that she was afraid for her life; she wanted out of her marriage but feared Gardner would kill her if she left.

In December 2004, Tammy borrowed money and filed for divorce, which was scheduled to become final on February 7, 2005. Friends, and her daughter described how Tammy “perked up” after filing for divorce and kicking Gardner out of the house. Tammy also remained fearful, as Gardner continued to call and text her, leaving threatening messages.

On January 23, 2005, Tammy was with her daughter when she began receiving text messages from Gardner, asking if she was going to go through with the upcoming divorce. Tammy did not answer. That evening Tammy visited with a co-worker, seeking help to “disappear” so that she could not be tracked. Tammy stayed with her co-worker for three hours, eventually returning home around 11 pm, when she called her co-worker to say she arrived home.


Just under an hour later, a 911 dispatcher with the Collin County Sheriff’s Office received an emergency call from a woman identified as Tammy. Tammy requested an ambulance, saying she had been shot by her husband. When questioned furthered, Tammy said Steven Gardner had shot her and then “left in a white pickup truck with Mississippi plates.” The dispatcher had difficulty understanding Tammy, as she was slurring her words and hard to hear. The dispatcher heard what sounded like choking and vomiting before the line disconnected.


As police arrived, they noticed a white pickup not far from the house. Police knocked but received no response. When they were able to gain entry, police discovered Tammy sitting on the bed, with a trail of blood leading to the bathroom. She was bleeding badly from her head. Tammy was flown to Parkland Hospital, and fell into a coma. After two days, she was taken off life support. She had been killed by a single gunshot to the head.


Police discovered that Gardner had borrowed a white pickup from his brother-in-law and credit card purchases put him in Texas, near Tammy’s house. Additionally, fibers were found in the truck that matched what Tammy was wearing. It was also discovered that someone had used a gun belonging to Gardner’s sister. Gardner turned himself into the police in Mississippi.


Please pray for peace for the family of Tammy Gardner and for all affected by John’s crimes. Pray for strength for the family of John Gardner. Pray that if John is innocent, lacks the competency to be executed, or should not be executed for any other reason, that evidence will be presented prior to his execution. Pray that John may come to find peace through a personal relationship with Christ, if he has not already.
