(AP) – A former police instructor accused of killing his wife and setting fire to their southern Kansas home is due in court Friday for a motions hearing on his case.

Thirty-5-year-old Brett Seacat is charged with first-degree murder in the death of his 34-year-old wife, Vashti Seacat, whose body was found April 30 inside their Kingman home. He also faces charges of aggravated arson and two counts of endangering a child.

The former Sedgwick County sheriff’s deputy taught officers at the Kansas Law Enforcement Training Center.

Seacat and the couple’s two sons, ages 2 and 4, made it out of the house.

Vashti Seacat filed for divorce 16 days before she died.
