KINGMAN, Kan. (AP) — A case that riveted the attention of many has culminated in the conviction of a former Kansas lawman in the death of his wife.

Jurors in Kingman found Brett Seacat guilty of first-degree murder Tuesday in the shooting death of his 34-year-old wife, Vashti Seacat, in their home just days after she filed for divorce in 2011.

Sentencing was set for Aug. 5. Prosecutors say they intend to seek what they call a “hard 50” sentence, which means Seacat would have no chance for parole for at least 50 years.

Investigators found Vashti Seacat’s body among the charred remains of the Kingman house where the couple lived with their two sons, ages 2 and 4.

Brett Seacat is a former police instructor. He claimed his wife set the fire and then shot herself.
