Vashti Seacat wanted someone with her and her sons when Brett got the divorce papers. At her last individual session with counselor Connie Suderman, on April 19, 2011, the two worked out a plan for her safety. Vashti had told Suderman she was afraid of how Brett would react. She was making plans to move closer to her sister and to work. [1]
Eleven days later, firefighters came to the family’s house in Kingman, Kansas. Vashti was found dead upstairs. Two days after the fire, investigators found her journal in her car. The last page looked like a goodbye. At Brett’s trial, two examiners studied it and came away with opposite answers about whether Vashti had written it. The jury convicted him of murder. [1]
The journal beside the bed
Vashti usually kept the journal on a table next to the bed. About a month before she died, Brett took it to the law enforcement training center where he taught and copied pages. He testified that she’d asked him to make an electronic copy to keep. [1]
On the morning of April 29, Brett opened the envelope with the divorce papers at his office. That afternoon he took an overhead projector out of storage and used it. He also destroyed some computer hard drives, threw away old phones and later bought gasoline. He said the projector was for work involving forgeries, the electronics were old and the gasoline went into his truck. The prosecution saw the copies and the projector differently. It argued that he’d used Vashti’s own writing to make a farewell look like hers. No witness testified to seeing him create the page. [1]
A neighbor remembers the television
In the early hours of April 30, a neighbor who couldn’t sleep was watching television. She heard a sound like a gunshot. Investigators checked what was happening in the program at the moment she remembered and put the sound at about 3:15 a.m. They had an estimate for when she’d heard it. She couldn’t see who was in the bedroom or who had fired. [1]
When an officer reached the burning house, Brett was outside and said Vashti had shot herself. The couple’s sons survived. After firefighters put out the fire, investigators found a gun beneath Vashti and a gasoline container on the bed. A fire investigator traced the fire to the hallway, from which it spread into the bedroom. The coroner found that a gunshot had killed Vashti. Tests were negative for smoke inhalation, and other wounds were consistent with rounds going off in the heat of the fire. The coroner gave no conclusion on whether the fatal shot was homicide or suicide. [1]
A difference in the letter d
Dennis McPhail, a Kansas Bureau of Investigation document examiner, compared the last page with samples of Vashti’s handwriting. He saw smears, tremors and places where a letter appeared to have been corrected. He showed how Vashti usually wrote a lowercase d and how the stroke on the last page differed. He concluded the page had probably been traced. [1]
Avis Odenbaugh, the defense examiner, looked at the flow of the ink and saw natural writing. She concluded that the person who’d written the other entries had written this one as well. She acknowledged some unusual marks but said tension or a person’s condition could affect the way they wrote. The disagreement mattered because it changed whose words the jury believed it was reading. [1]
The testimony about Vashti
Suderman told the jury that Vashti had seemed depressed when counseling began but that her outlook had improved by April. She remembered how often Vashti talked about her sons. Vashti had told her she wouldn’t take her own life, citing her faith and her children. The defense offered evidence it said showed Vashti had been in distress and argued that she had set the fire and shot herself. Her earlier plans and the history of depression were each part of the testimony. The jurors still had to weigh the fire, the fatal shot and the disputed page. [1]
In 2013 the jury convicted Brett of premeditated first-degree murder, aggravated arson and two counts of aggravated child endangerment. The judge imposed life with no possibility of parole for 25 years on the murder count and a further 75 months for the other counts. The Kansas Supreme Court affirmed in 2016 after reviewing what evidence the trial judge had admitted or kept out. [1]
The last page drew the examiners’ attention because it looked like Vashti was saying goodbye. Suderman could testify to a different moment, one she’d been there for: Vashti was planning how to get through the day the papers were served and asking who could be with her and the boys. [1]
