(AP) — A former Kansas lawman on trial for the death of his wife says she had mixed feelings about asking him for a divorce.

Brett Seacat testified Thursday at his first-degree murder trial about his work as a police instructor and former deputy. He talked about the day he was served with divorce papers.

And he recounted his last day working at a law enforcement academy before the April 2011 shooting death of his wife, 34-year-old Vashti Seacat.

Brett Seacat is also charged with aggravated arson and two counts of child endangerment for allegedly setting fire to the couple’s Kingman home. He and the couple’s two young sons escaped the fire.

The defense contends Vashti Seacat set the fire, then committed suicide by shooting herself.
